hey jeepers,
fruityloops should do the job just great.
to record straight to an ipod, you will probably have to get one of these gadgets:

i've used the iKey before, but earlier version they needed to iron out some problems with reliability.
the newer version is cheaper and so much more improved, it even comes bundled with microphones.
I'll be evaluating it soon...
other than that, some tips for recording e-drums (i'll try to make it as straightforward as possible) for typical windows PC
1) line-out of your e-drums (can be RCA (red-white), stereo 1/4" or 1/8") goes to
line-in of your PC sound card or built-in sound (usually a stereo 1/8")
2) make sure your recording from the line-in
- double-click 'volume' in task bar (lower right hand corner)
- go to 'options', 'properties'
- click on radio button for 'adjust volume for ...recording'
- check on the 'line in' box, and uncheck the rest (not entirely necessary, experiment a bit)
- set the level, and play around with it
3) Back in Fruity Loops, go to 'Channels' , 'Add a Channel', 'Audio Clip'
- Click record, play something, and see if sound captured
- Adjust from there
Hope this helps, feedback if more issues encountered!
cheers
