If you can afford the 4k TP for a +6 supreme tome right now this may not be a bad build for you:

It is 36 pt but you can shave off 2 pts from WIS and STR and still do just fine with 32 as well.
If nothing else the enhancements are not a bad starting point.
The only tome you really NEED to have as a ranged rogue build is a +5 DEX, it will help you meet pre-reqs for DEX based feats like Combat Archery (DEX 21) and Improved Precise Shot (DEX 19) it might also be on sale atm but not sure.
