Help me making this monk with rogue splash

[matezzo]

Friend wana try monk, and I haven't played one so looking for feedback:

Race should be halfling,mostly solo build so would be nice if had at least open lock. search/disable is a bonus as well as umd.

So one rogue level at least. Then i was thinking if he takes one rogue he might as well specialize for staff because there is a nice synergy there. And if He can't take the capstone He might as well look for a third class and druid seem to offer a lot just for one level (rams might and that quarterstaff enchant). A second rogue would give access to +1 att +2 dmg, enhancement the quickstrike with lower cooldown and haste boost.

I think It would begood to invest in dragonmarks for this halfling and even in empower heal (first maximize then swapped to empower heal later).

Feats:
Monk1-THWF
monk2-PA
monk3-?? I guess cleave is not a monkfeat, right?

7 other: 2*THWF, dragonmark, empower heal, imp crit, ??

third monk feat probably dodge, last feat probably cleave, but want to hear other ideas. (edit* if less than 18 monk levels then I might go for grandmaster of forms here..not sure if it's worth a feat though..)

Stats: 14 starting str, level ups here. Dexterity build would benice, but overall I think str is the way to go.. 17 needed for GTHWF anyway + rams migth,+fire stance quite good.

Wisdom is lowish.. I'm not sure this build needs it at all, excpet for some ac and will save.

Some questions/feedbackasking:
-how to split the 3 classes? maybe an other good monk/rogue combo?
-how important is to use the monk finishers? i rolled up a veteran lvl 7 char and got overhelmed with the many differnt attack
-What i really miss in this build is the cc ability. A thief acrobat would have at least a good trip attack. Is there a good option for this character?
-I'm not sure monk has good surviability without prr/mrr.. am I right?
-how good are the monk spell like abilities? Is it worth to try to invest in spellcraft?
-how to give this character some good ranged dps without changing too much. Doesn't ned to be great, but usable occasionally.
