Twoster,
Sometimes XP3's have come with biomedia (mine came with ceramic rings), but when they do, it's most likely for promotional purposes, and I don't know how much the company thinks that promoting the filter (it's quite popular) is necessary.
Almost any biomedia would be fine as long as it fits in the basket (or baskets if you really want to load up on it). I used the ceramic rings and stars. I've also used Fluval biomedia, Aquaclear's biomax and lava rock in other filters. I have heard that Eheim's biomedia is good as well.
For the jet nozzle and spray bar, try each one to see which you/your turtle prefers. How big a tank is the filter in? Since your turtle is quite small, the spray bar has a more gentle output, and if you put it under the water's surface, it would be very quiet (same for the jet nozzle). To me, the jet nozzle isn't THAT powerful, you can adjust the output with the spigot on a piece that's before the nozzle, but it's not good to keep it turned way down for long periods of time. I've never tried both at the same time---how would you do that and why?
I've never used the bio chem zorb, just activated carbon. The water doesn't have to run totally clear with the carbon (it would take forever) I'm assuming that it wouldn't have to with the bio chem zorb either, but try to get the color as faint as possible. You're really rinsing off the excess.
