Leshma, I think that if you got a +3 bow (longbow), your accuracy will be good enough, even with 150 (just go to train regularly on DTV), and about melee, 50 is already efficient with high athletics skills, combined with 6/7 PS.
About my build, I'm using 21/21, since that PD improves your arrow's trajectory, speed, and damages, it helped me to kill armored players
Level 34
Strength:21
Agility:21
One Handed:45
Two Handed:39 (for the lulz, just put everything on 1h
)
Archery:155
Weapon Master:7
Athletics:7
Iron Flesh:1 (can go for 4 IF at 35)
Power Strike:7
Power Draw:7
This build is quite effective at level 35, because of high amount of hit points (64 hp), combined with speed and enough strength to kill heavy targets at melee with some stabs.
Since I only used longbow, I think that 7 PD is a must because of the bad missile speed of this bow, but if you get a rus bow, it may be effective with 6 PD :p
Just make some tests with an STF about every factor of your future char.
