Sounds like a nice build. It will be strong on buffs, very strong on damage (since the sneak attack will work with the bow, and this damage bonus will cumulative with the AA damage bonuses [img]smile.gif[/img] ) but quite weak on HP and AC so you will need to get used to deploying hit and run tactics - although the Rogue's stealth ability matches with the grace of the AA quite nicely.
I think robertthebard here tried an AA/Cleric/Bard which had some truly great buffs. Yours will have less impressive buffs but the potential to be more damaging through the Rogue's sneak attack ability.
BTW if you're playing SoU -> HoTU with the same character, expect to finish at about level 28 tops, but that's still enough to get a good 10 levels of AA (although you should consider taking this even higher if you can, since the AA is one of the few priestege classes that continue to grow in power significantly in the form of regular attack and damage bonuses past level 10). You might like to consider an AA(10)/Bard(10)/Rogue(8) build which will give you a good balance of rogue abilities, spell casting (up to level 4), buffing (via bard song) and great ranged attacking ability. If you wanted to push for some more powerful spell casting at the expense of some ranged attack power and/or some rogue abilities, you could take 16 levels of bard in order to gain level 6 spells and a stronger bardic song. It's entirely up to you how you balance the classes.
