Can't recommend a hard drive, but can recommend this:
Interface: Echo AudioFire 4
http://www.echoaudio.com/Products/FireWire/AudioFire4/index.php
You're looking at about $300 or less here, but I love Echo products and own
a Layla 3G. Underrated stuff IMO. The audio fire will give you six ins/six outs and two decent pre-amps as well. I use the pre's on my Layla, and sound decent and should be the same pre's.
Mics: a lot of options here. I own CAD M177's and they are great mics that work on a variety of different sources. You're looking at about $100 for one. The CAD is a large diaphragm condenser mic, and requires phantom power (which
the Echo AudioFire 4 will provide for). There are what seems like millions of options in the budget condenser category, but I stand by the recommendation of the CAD.
Doesn't hurt to have the old stand-by dynamics either -
Shure SM58 or SM57. I have a few of each I use live, and in the studio from time to time.
Software: you could opt for the higher priced stuff (Sonar, Cubase, etc.), but if you're just getting going, I'd look seriously at Reaper:

Lots of people love this application. I tried it and thought it was pretty cool myself, but use Sonar 6 for my work.
Buy a decent pair of closed-ear headphone for monitoring. There have been a zillion recommendations for "cans" around here. I use a pair of AudioTechnica MTH-M40fs cans and love them for tracking. Do a search for MoreMe's around here - a cheaper and useful option.
Monitoring: a pair of powered monitors would be important for mixing. Again, a zillion recommendations for those around here as well. I use a pair of Tannoy Reveals with a Hafler TA1600 amp (the amp is not longer available). Works for me. Whatever you get, you "learn" the monitors and work your mixes to help them translate to other systems (boom-boxes, car stereos, etc.)
And now if you really want to dive in, let's talk acoustic treatment:

Good luck and have fun with it. But beware - soon the disease will infest you - the one where you can't stop buying new and better gear!
