"these things add up"... Man you hit the nail on the head..
Going to need: A good
Power supply
Coax (lmr400 if you can swing it)
Antenna ( you can build a dipole on the cheap, although I would recommend a multiband vertical so you can work many bands )
Parts for a good ground at the bench
Electrical tape (I use silicone tape over electrical tape for outdoor coax connectors)
Tuner if the radio doesn't have a tuner (not all tuners are created equal, prefer automatic tuners as life it too short to tune every spot on the bands)
Ballun: You can make a ugly balloon which works pretty darn good. Just need to know how many turns to use.
Rf coming back into the shack is a lesson all hams learn very quickly.
Band chart: I keep this chart on the bench all the time for reference..

Things that are really nice to have:
Elmer: If you don't have an Elmer start looking, this is one of the most helpful things a new ham can have..
Antenna Analyzer,
MFJ 259C The analyzer is one of the most useful tools (In My opinion), I am always tinkering and checking the antenna. If you are going to build an antenna it is helpful in trimming dipole lengths. Might be a little pricy, I have a 10 yr old MFJ 259 which has worked well. I like having SWR and R (ohms) to know how well the antenna is matched to the radio (50 ohms). If you don't have one you can probably borrow one from a local ham.
Locating Amateur operators in your area.
FCC Geosearch select address , zip, and say 5 miles.. This will give you a list of Licensed Hams in your area.. They may not be active so this is just a reference...
Good Luck and start learning. Imo I would try and locate a radio which has an internal sound card so you can easily do digital modes.. But for now just get on the air and have fun.. Don't hesitate to ask more questions and shoot me a IM if you need to talk..
