do Enhancements stack
Yes it will, but after the third enhancement of the same type the buff gets alot smaller.
Yes, but only up to 3. After that, it's pretty well useless.

ok thanks for the info
I'd recommend quickly making another character and running through the tutorial, and read everything that's there. There's a very nice explanation of enhancements.
The "up to 3" does not apply to Training Origin (TO) nor Dual Origin (DO) Enhancements and affects SO's minimally. It doesn't significantly impact single aspect IO's (which enhance only one aspect of a power, such as Damage, but not Damage and Recharge Reduction) until you use L40 or so Enhancements.
Also, just about all powers can be slotted with more than one of any Enhancement, I.E., you can put more than one Accuracy or more than one Defense or more than one damage. A somewhat typical slotting scheme for an attack using SO's (usually only usable at L22 and higher) would be:
ACC x1
DAM x3
Recharge x1
Endurance Reduction x1
Slotting something like Maneuvers would be:
Defense x3
Endurance x1 or x2
