Yes, you can use standard C64 roms. The only differences in the SX-64
roms are
* lack of tape routines
* default to device 8
* different startup colours
Roms autodetect PAL and NTSC and adjusts the timing accordingly.

It's not an issue with the 6526.

Yes, and the VIC chip, and you might have to do cut a jumper or two on
the CPU board.

It'll show a rolling black and white picture, but you should be able
to adjust the vertical hold to get a stable image. To get colour you
will need to replace the video board with one from a PAL unit.
Not that I have tried any of the above, but it should be fairly
straightforward.
