If you want to be a good archer, you don't waste time on a PrC at all. A straight Cleric 20 makes the best archer.
Elven (preferably Wild or Wood) Cleric of Solonor Thelandira (FRCS)
We'll give him 19 Wis and 10 everything else (to make life easy).
Domains:
War: Free weapon focus (longbow)
Elf: Free point blank shot. Notable spells:
true strike - 1st,
cat's grace - 2nd.
Feats: Extend Spell, Persistent Spell, Rapid Shot, Precise Shot, Far Shot, plus any two others (I prefer item creation or empower spell).
Get up in the morning and cast the following:
Persistent
divine favor (5th level): +6 luck to attack & damage for 24 hours
Persistent
divine power (8th level): 18 Str, 20 temporary hp, BAB -> +20/+15/+10/+5 for 24 hours
Cat's grace (2nd level domain): 1d4+1 Dex for 20 hours
Greater magic weapon on bow (4th level): +5 enhancment to attack and damage for 20 hours
Greater magic weapon on 50 arrows (4th level): +5 enhancment to attack and damage for 20 hours
For equipment, I'll just take what I want: the bow.
+1 mighty [Str +4] composite longbow of speed: 50,800 gp.
Thus:
Code:

Note this is with Dex of 10 base + 2, and only one magic item. Oh, and he's only used 1 8th level slot, 1 5th level slot, 2 4th level slots, and the 2nd level domain slot. The rest are still free.
Like the 10th level DS, I can
true strike once per day, except I've been doing it since level 1 instead of level 15. Oh, and I could prepare it in my 2nd or higher domain slot if I wanted to, too. And, hey,
true strike negates concealment, even 100% concealment. Of course, both
see invisibility and
true seeing often do, too.
I don't get the OotBI's Superior Weapon Specialization, but
divine favor is better. I don't get melee shot either, but how big of a deal is that exactly?
I don't get AA's enchant arrow, but
greater magic weapon is supremely better. I can use it on the bow and the arrows, and I can enhance my party's weapons, too. i don't get Imbue Arrow either. Instead, I just cast the spell directly. And
my caster level is maxed.
