Guided arrow is an horrendous skill for PvM (except for bosses, where is kinda helpful).
If you're going to use WF, this has to be your skill distribution:
Max Strafe
Max Magic arrow (I've found it very effective against phys immunes, better than Freezin' arrow)
Max Penetrate
At least 17 into Valk, +skills included, or just max it
At least 16 into Crit strike, +skills included
1 Pierce (or more when you have skill points left @ higher levels)
Some more into Multiple shot if you need more arrows

Your gear has to be intended to catch the last attack speed breakpoint with strafe (120% ias if using Windforce).
So:
- Wf has 20% ias (40% if shaeled)
- Laying of hands (set gloves) have 20% ias
- Highlord or Cats eye have 20% ias
You need some more ias, at least 40%, to catch the last bp. You can use:
- Andariel's visage with an ed / ias jewel + Nosferatu's coil unique belt (= 45% ias)
- A 3x ed / ias jewel magic elite helm with life (= 45% ias) + Razortail (= good pierce, and more damage)
It's up to you. The best armor for your zon, if you're non ladder, is a Chains of Honor Dusk shroud. But if you aren't that rich, you can use a "Lionheart" Dusk shroud (Hel + Lum + Fal) or a "Duress" Dusk (Shael + Um + Thul).
Now, in ladder, the best armor for a bowazon is a "Fortitude" Dusk shroud.
