Maxing Out Dex for Halfling Light Monk

[blumsborres]

Hi there, I'm a noob to the monk class. I've been reading up on different builds and I see that alot of them rely on tomes to get stats up the spec. Let's just suppose that I can't afford tomes (unless I pick them up of course). I also have no plans of reincarnating (I see alot of talk about 34pt builds). Would the following stats be fine to start with? Please give me your insights.

Hafling Monk (32pt Build)
STR 12 - sarificing DPS for better WIS
DEX 18 - AC + TWF requirements - trying to save on tomes
CON 14 - i've been told that this is satisfactory
INT 8
WIS 16 - AC + Special Attacks DC (+5 this is my level stat)
CHA 8
