If you want to go with an AR platform, you need to get familiar with all of the intricacies of the platform. AR15.com and M4Carbine.net are the two best sites to get on to find everything you want to know about ARs. Spend a decent amount of time researching the difference between a carbine gas system and a midlength gas system.
Here's the Cliff's Notes in relation to your questions:
The "Best" brand is highly subjective to the user and the current market. 5 years ago, Colt was the undisputed King. Now you have companies that have surpassed Colt for innovation, options and features. Colt is still good, but it would be inaccurate to say that there is one brand that stands above the rest.
Colt, Noveske, Bravo Company Mfg, Knight Arms, Daniel Defense, LMT, LaRue Tactical, the list goes on. The key is to find a rifle that has a reputation for reliability, durability, and more than anything, consistency with build quality.
For ~$1000 for the rifle, you have several options.
Colt 6920
Sig Sauer M400
S&W M&P15
Spikes Tactical ST-15
Rock River Arms Entry models
Armalite M-15
All AR rifles owned by Cerberus/Freedom Group (DPMS, Bushmaster, Remington) essentially use DPMS components for most of the parts. DPMS has absolutely terrible Quality Control and Quality Assurance. They produce a lot of parts and they don't sufficiently check to ensure that everything is in spec. Every time I go to firearms training courses or other related training, I run into cops and LE agencies that have been screwed by DPMS. I'm not talking about bad prices either. A major metro county SWAT team got new DPMS rifles and ALL of the springs were bad. All of them. Another agency got DPMS AP4 carbines for their squad cars, and on the first range day, the rifles literally started falling apart; extractors, ejectors, pins, the works. Two agencies I've talked to have received bolt carriers that were not chrome-lined. When they sent the BCGs back, DPMS just replaced the gas rings and said they were fixed. A quick check revealed no chrome lining inside the BCG, yet again. A lot of companies use DPMS small parts, but they do a lot of QC/QA inspection on the parts prior to accepting them. Those companies wind up sending a lot of rejected stock back to DPMS. So basically, stay away from DPMS, Bushmaster and Remington. The first AR I bought was a DPMS eons ago when they were still halfway decent. I have replaced half of the components on that rifle, which should not be necessary.
I know DPMS is a Minnesota company, and I always get flamed for saying this because you can't bash DPMS in Minnesota. I still do, because I've read the armorer reports and talked to the other LE armorers around the state.
The reason why I bring this up is because outwardly, DPMS rifles do appear to be very affordable. You get a lot of rifle and options for what you pay. The rifle barrels that DPMS has built by other companies are typically very accurate. However, people tend to mistake accuracy for quality, and mistake affordability for real value.
Several people shoot 7.62x39 ARs, but if you want to shoot that cartridge, the AR is not the platform for it. The cartridge has a high amount of taper, and this causes a bolt thrust issue that causes feeding malfunctions and results in much higher instances of damage to the bolt. It's better to stick with a 5.56mm rifle and be able to shoot it more reliably. Steel case .223 ammo is nearly the same cost as steel case 7.62x39, so if cost is a concern, you can still come out without issue by using steel case ammo instead of brass case (just invest in an extra extractor to keep in your range bag). If you really want to shoot the 7.62x39, get yourself an AK variant. They were made for the 7.62x39; the AR wasn't. The fact that the 7.62x39 is a heavier cartridge is irrelevant for most people, since they use their ARs for range shooting.
If it's a hunting issue for needing heavier rounds, you should be considering a more appropriate cartridge like the 6.8SPC, 6.5 Grendel, .300AAC Blackout, or a .308.
The talk about different lowers and uppers is that the AR is sectioned into two components. The Upper Receiver group and the Lower Receiver group. The Upper houses the upper receiver, bolt carrier group, barrel, gas system, handguards, sights, optics and muzzle device. The Lower houses the trigger and hammer assembly, safety, magazine release, bolt catch/release, grip and buttstock assembly. You can buy one lower and then buy or build multiple uppers to use your rifle for whatever you want. You can also completely custom build your rifle from the ground-up with every specific component that you want.
With that said, I would highly recommend that you stay away from building your first rifle. You can have one built for you, or have someone knowledgeable assist you with building one, but going at it on your own without having the knowledge about the platform will be problematic. I spend a lot of time cleaning up mistakes people make when building their rifles. Shoddy components, parts installed incorrectly, wrong torque specs, wrong parts used, parts incompatibility, etc. As a general belief, I think that the novice AR buyer should buy a completed rifle. Keep it simple. Crawl, walk, then run.
That's just my $0.02.
