Yes the xp3 does alot of work and am very glad I added it. At your current stock level your two AC110s should do the trick. I added the canister as my fish grew to adult size.
To answer your questions on micro bubbles, the only time I get any bubbling is when the tank water level has dropped due to evaporation. The only other reason to get any air would be on the suction side of the filter. Check the inlet for any cracking in the plastic arm that would cause air to be drawn into the filter.
If I were to do it over again I'd probably use 2 XP3s. I've found them to be a wonderful filter if maintained properly.
Always plan for the future but never try to predict the outcome.
