If you're using the composite out, you're stuck with either 640x400 (NTSC high-res interlace) or 640x512 (PAL high-res interlace), depending which standard your TV uses, though the interlacing means its going to flicker like hell. (I'm not sure which continent you're on) For higher resolutions, I'd use the rgb port with an adapter, with the super-72 monitor driver, you can get up to 800x600 resolution. (Mine is set to that @ 64 colors for speed purposes, even with Fblit its too slow in 128 or 256 colors) There's a monitor driver around somewhere that goes up t0 1024x768 on AGA, but I wouldn't use it. (Eats chip mem) As far as the mouse issue, I use a Mr. Mysza that my brother gave me because it wouldn't work with his kvm switch, so as a standalone it works fine. (Using with a alpha data joystick switch + 6-button sega controller, mr. mysza to ps2/usb adapter to usb to wireless mouse base) I believe there's other threads about the ps/2 adapter/kvm issue, though.
