Re: New to warmwater
AKJay- for bass, especially Texas bass, you're probably better off with the 8 weight not only for the size of the fish and heavy cover you might run into, but mostly for the size of the flies you'll be throwing, typically size 6 and up.
I'd think about covering the water column, here's some typical bass stuff (and some Alaska trout/salmon stuff that would probably work great for them). And if you fish for pike up there, probably any of that stuff would work too. Don't feel like you need all of this, but just some typical examples for bass to cover different layers:
Topwater-bass poppers, spun deer hair bass bugs, gurglers (AK stuff like poly wogs, large stimulators, mice, grass hoppers, large stuff tied with foam)
Suspending stuff- any large streamers like muddlers, bucktails, marabou feather wings and stuff made with synthetics, zonkers etc. Any stuff you have here will probably be fine. If you wanted to tie some things up, a lot of the baitfish bass feed on like bluegills and shad have a large profile top to bottom, so deceiver type flies (with the traditional saddle hackle tail or just a sprig of bucktail for the tail in all white or "fire tiger" might be good choices). "EP" fiber type flies are also popular but can be a PITA to cast and tend to get mangled after a fish.
Floating/diving- Dahlberg Diver (Pike type megadiver)
Deeper water- clousers, crayfish, woolly buggers, leeches (egg sucking leeches, large heavily weighted nymphs, weighted rabbit strip flies)
I don't think color matters much for top water, but for other stuff mix it up a little. A good assortment would include some black, chartreuse, which tend to be good in murky water, yellow, white (for shad), brown and olive and some with a bit of flash. Again, you probably already have a lot of stuff already that would would great for them.
If you can bring the four weight too that should be a blast for panfish you'll probably run into.
