Dude 6 level isn't that far. And you might want other feats down the road that you could take now (like Combat Reflexes, Imp Init, Dodge, etc) that don't have as high a prereq. And check out OA for the exchanging of Monk abilities at 1st, 2nd, and (I think) 6th for feats from the Martial Arts lists... You might be able to drop Deflect Arrows at 2nd for one them
TTFN
Edit: For those without OA, it allows for Monks to exchange a class ability (Stunning Attack at 1st, Deflect Arrows at 2nd, and/or Improved Trip at 6th) for a feat chosen from the Martial Arts table. The Monk must meet the prereq's for the chosen feat. The feats Weapon Focus, and Weapon Finesse aren't on the list, however your DM might allow you to get them to fit with your Monk's fighting style concept (I would as it isn't that big a stretch, and then you could get them at 2nd and 3rd level...)
