The 10000 spool will take 170m of PE8 so I think that you'd be looking around what the guys have advised - from 200 - 220 yards of 80lb TF XP.
As to whether 80 or 100lb is better, it really comes down to the area you're fishing and the size of the fish you are likely to encounter. There is no doubt that 80lb TF XP casts better than the 100lb and in the case of TF XP, it's quite noticeable. The 100lb, especially in white, feels quite waxy and tends to stick a little. On the other hand, if you're fishing in a tough location, you will have hell on 80lb if there are decent fish around.
The colour is not important to so go with what you like. I personally prefer white or yellow myself.
