what you're talking about is illegal and we don't support that here. Buy the software...it's worth it and you don't get into any problems...
You still haven't talked about budget, so I'm going to assume that you don't have too many money issues. Here's an example of a good firewire setup that you can use... first some theory - every recording system uses a 'signal chain'. This is the path that sound travels along to be recorded, monitored, and mixed down. I'm going to talk about what an example signal chain for you looks like, and also talk about why each element is essential. Your signal chain should look like this: Mic -> Preamp -> interface -> Computer and recording software -> interface (same one) -> monitors
For mics, you can get away with only having 5 mics, but most of us end up getting more for variety. THe five mics you need are, 1) a large dynamic like the AKG D112 - used for kick drums and bass cabs, 2) a small dynamic for snares and guitar cabs like the SM57, 3) a large condensor used for vocals and room like the SP C1, 4/5) a pair of small condensors used for overheads like the MXL 603's. With those five mics you can record drums, guitars, bass and vocals easily with decent results.
A preamp is neccesary. You've got some that are seperate, boxes that are just preamps like the DMP3, or some that are built in to other things like a mixer or an interface. People here have been recommending getting a set of pres built into an interface, and this is generally a pretty good way to start. The Firepod will give you great resuls and it has pres built into it. Basically, you want to start with a pretty reliable set of "workhorse" pres - these are pres that you will be able to rely on even if you start to add more specialized pres. Having four to eight workhorse pres is a great thing to have, and I suggest some boxes like the M Audio Octane, a few of the DMP3's, Focusrite Octopre or the Presonus Digimax.
An Interface turns your analog signal into a digital signal your computer will recognize. Firewire is the newer way of doing this, and I would suggest it for you along with the guys above. The Firepod is one way of doing it, but I like M Audio's gear personally. I would suggest picking something like the M Audio 1814, it gives you 18 channels in and 14 out. This would be great for you because it's expandable - you get 8 workhorse pres now (like the Octane) and add more as you want/need them on a 1 or 2 channel basis.
For software, I use Cubase SX, and I haven't used to many others that i like. I suggest you look at Cubase, and also look at Pro Tools M Powered - if you get into the M Audio gear it allows you to use a M Audio version of Pro Tools - Pro tools is generally what pros use, and so if you have a chance to use a version of pro tools for 250 bucks it's a good idea.
Monitors are CRUCIAL when you're setting up a home studio. Buy the best you can afford, and DO NOT skimp here to get that extra mic or pre that you don't need. Good monitors pay for themselves when you're mixing! I'm a big fan of Event monitors, and I'm also a fan of the Mackie HR series of monitors.
After all that you're going to need to think about cables, sound treatment/ control, storage, mic stands and all sorts of other little items that eat up your money when setting up a studio. I suggest you take your time, set a budget, and then do a lot of research before you just go start buying things. Once you've done your research come and ask questions.
Hope I helped,
