I'm fairly new and want to run the Super Mario Bros. any% category. Any recommended timer? Also how do I know exactly (down to the millisecond) how well my run was? I'd be thankful for any help.

BTW I use FCEUX 2.2.2 for my practice emulator and my Wii for my real gameplay.

LiveSplit As for millisecond, well, you'll probably have to split manually, but you'll get used to it (AKA you'll split at the same time everytime at some point, if you concentrate that is).
