Archer in need of help! D:

[AnimePwns:]]

I'm currently a lvl 22 Hawk Archer, I just have a few questions.
Which build am I suppose to do?
1.All dex
2. 25 SPR than dex
3. Str and dex

Question 2.
Should I sell my +6 bow for a cross bow? Or should I keep it? Or enchant it?

And final question
As a total n00b to Fiesta, I'd like to ask where should I train from lvls 22~30?
And 30~40 if your kind enough!

Thanks!
Anime~
