Here's the core components of what I'm playing right now. There is a
2 Monk/18 Rogue build on the forums that may interest you.
I think the 2 Monk vs. Capstone arguments are a lot like taking 2 Artificer on a Mechanic build. Each has it's advantages, but neither is a bad choice.
Note: I'm working off memory right now. If I remember to, I'll clean up a couple questions later when I have DDO open.

*Whatever* I currently have Technician.
Cocoon
Tactics:
Do flips as you enter combat. It kicks off the acrobat capstone which is a cross between Dance of Death and Balanced Attacks.
Keep Lightning Mace and Quick Strike on timer. They both stack.
Dire Charge and Sweeping Strikes will be your crowd control. Sweeping strike's cooldown is stupid long though. (And according to the wiki, too long for the advertised cooldown.) But, IMO, it's worth having for the 100+ trip DC.

Plus I get up to 10 more with Nimbleness. But I like maxing out my dodge around the same time I get a good blitz going.
