I won't get into brands (each their own), but I can give you a nudge in the right direction as far as the weight of the outfit you might want to look into.
It sounds like you could do your fishing with a 5 or 6 weight outfit. If you're sure that the bass rarely get over 15", these weights will let both panfish and bass show off well during a fight. Bear in mind that if you plan on casting larger flies, you may be more comfortable with the 6 weight or even heavier.
The 5 or 6 weight would also work well for trout. Keep in mind the size of the flies you'll be casting....throwing streamers and weighted nymphs is easier with a 6 than a 5. I try to use as long a rod as I can get away with when trout fishing because I do a lot of nymphing, and a long rod gives better line control for mending. But if you fish canopied streams, a 9 foot rod would be impractical.
Good luck with your search, and if possible cast before you buy.
