I am new to this too, but here's something you will like.
There are software programs that will play bass, drums, keyboards, etc. for you. Reason 2.0 is BY FAR the best and most popular of these. It's in the $200 range, if you buy it.
Even if you bought a stock computer from Dell (which I did), you could still learn the in's and out's of digital recording.
Here's what I would recommend you do.
1) Good workstation computer.
2) Cool Edit 2.0 (or whatever the newest version is)
- This program is for recording and editing of audio only. Anything you do from Reason 2.0 - drums, bass, etc. - will have to be imported into Cool Edit. That's no big deal, though. If you wanted to spend the money and were going to be doing a lot of MIDI (which you probably won't), I'd tell you to get Cakewalk Sonar 2.0 or better.
3) Reason 2.0 (or whatever the newest version is).
- This is an easy to understand and use program that will enable you to do everything from drums and bass to so much more. I downloaded mine and have never been able to crack it. As soon as I get the money, I'm buying it. I'm currently using the very limited demo version.
4) M-Audio Audiophile 2496
- This is an outstanding soundcard for digital recording. You can play audio and midi through it at the highest bit rates available. It's also the cheapest soundcard you'll find. You could use a crappy Soundblaster, but don't waste your money on one.
5) Headphones
6) Shure SM57 microphone
- This mic will record vocals and insturments at a very high quality. It's also very cheap. It's the industry standard.
All that will get you started. The software is the only expensive part. I downloaded all mine for free. Try demos of the software before you buy . . . if you buy.
At this very moment, you could download Cool Edit 2.0, plug your guitar into your POD, plug into the aux-in on your soundcard, and record your guitar.
I play guitar. I've been in bands my whole life. I'm currently solo. I've recorded a demo in a "real" studio, but other than that I'm no expert on this stuff. That sight mentioned above will really help.
