I'm pretty sure that GB only works at 16 bit 44.1kHz, which means that you will not be able to produce a recording of equal quality to Logic or DP, both of which can easily handle 24 bit 96kHz, have output sections that allow for plugins to be included on the stereo output (limiting being the most common), and have the ability to output more than just a stereo mix (among a litany of other features). Perhaps the biggest difference here is the bit depth. The greater the bit depth the wider the dynamic range, and the better that low level information survives throughout the process. GB is an incredible app at its price point, but in no way can hold a candle to a modern Pro app.
Well if by final mix you mean mastering then yes, that is how things are generally done. Is it necessary? Good mastering is the difference between an album that just sounds well recorded and an album that sounds cohesive, articulate, transparent, and consistent, so while many local releases may go unmastered it really is a very important part of the process.
The first part of kankers post is pretty much on the money, with the proviso that the vast majority of commercial releases are still at 44.1/16 bit due to the CD Red-book standard, so part of the advantage of 24 bit HR recording is lost.
That said, I regularly use GB as a tracking platform, and you can use pretty much all of the same plug-ins in GB as you can in Portools or Logic (RTAS that is).
The second part would bring howls of disagreement from most engineers and producers, in SOME cases mastering will help a recording to become better that it otherwise would be, but most professionally mixed records are as near as dammit, and the mastering process is a means to that end.
Of course some mastering engineer are really worth their money, and can make a real difference, but the changes made are usually very small and very specific, often simply correcting errors induced in the original by inconsistencies in the monitoring during the mix.
As to the original question, the software is less important that the knowledge and talent. you can make a world-class recording with 2 mics, 2 pre-amps and a DAT machine, but you've got to know how, and the mics and pre's have to be world-class to.
GB is a very good place to start, it's capable, but it's easier to work in Protools or Logic or the like.
Learn your signal path and mic techniques, learn your MIDI and sequencing, then worry about the mixing.
