It's going to be a lot of trial and error from here, my friend. In the CONTROLS folder within the ZiNc directory, you have to manually change your button assignments for each game. Make sure you also set up the Settings.ini file to match your appropriate ROMS path. I just point mine at my MAME ROM directory. There's no easy way to really figure out which button is which. What I did was I used Aldo's ZiNc FE and entered them in (in a seperate folder of course) and then copy and pasted the button assignments into my files in the CONTROLS folder. As far as Joy2Key goes, you can open Joy2Key.exe and edit the key assignments easily that way. I used Street Fighter Alpha to test all my button assignments and once I got them just right, I set the controls up like that for all my other games in that BIOS. Then, I moved on to the next one, and so forth, and so on... Don't get into a frenzy, bud. It took me a week or so to get everything just so.
