You will find that the more you get into it, the more creative ways you will find to make due with what you have. I have to admit that I have came up with some cool (and probably dangerous) ideas when either I couldn't be bothered to get up to the hardware store or I thought StewMac was too expensive.
Here is some other stuff you should get.
Razor Saw (for slotting fingerboards..Exacto makes them)
Arbor press (only 30 bucks at Harbor Freight)
Clamps Clamps Clamps Clamps Clamps
Hand Planer
Good Random Orbit Sander (MUST HAVE!!!)
Is there any way that you could rent a storage room?
I tell you man, the more you get into it...the more stuff you will collect.
You will find yourself making jigs, storing woods, buying new tools and lord know what else.
Hell, my addiction has grown so bad that I'm about to move out into the country so I have the space to build my workshop (I call it the woman haters club).
Good luck with it
