Hi, sorry for this long and constant barrage of questions, I'm new to this and have read so many guides recently my head is spinning and I could do with a little clarification. If someone could offer any advice, I would be most grateful!
Bought a Jamma Cabinet (2 sticks, 6 buttons per player plus P1 start, P2 start) which I want to use the controls and monitor, and add a couple of extra buttons for emulator functionality (Exit [ESC], Options [TAB], Credit [5]). Are there any other buttons I should add?
Have an old PC powerful enough to run all but the most recent games running a clean XP install from a 9 gig drive, which has a 20 gig drive that I am hoping to keep my Mame collection on.
What is the best way of removing roms from a collection so that I can fit it all on the 20 gig drive? Would removing clones be the way to go? Is there an easy/safe way of doing this? Will there be any issues of having the Emu & front-end on the boot drive, but the roms on a second drive?
Any recommendation for front-ends? Frontend needs to work on WinXP and be extremely easy to set-up and use. Would like it to boot and hide Windows as much as possible (but would obviously need to get at Windows later if I need to make changes to my set-up). Would prefer one that I can use to run multiple systems with later (might add C64 games to the cabinet at a later date). GameEx looks awesome (with the videos, screenshots, favourites/recent lists, etc), but also looks like it might be difficult to set up.
I haven't yet bought J-Pac and ArcadeVGA but in the next few days I might have the chance of getting an old version 1 card cheap - are there any major differences between the two cards? Would the old card work fine? Does the new card make things any easier to get set-up? (Trying to do this on a budget) I've read some horror-stories about installing ArcadeVGA - Would it simply be a matter of getting my set-up working with the PC's existing gfx card, then switching the ArcadeVGA in and installing that last, or should I install the ArcadeVGA first?
Setting up J-Pac - is it as simple as fitting it in the Jamma slot, connecting it to ArcadeVGA, and everything should work? Is it easy to get the complete set of player buttons working?
Am I going about this the completely wrong way?
Help

Thanks!
