Sunset..I have quite a few years of flyfishing for bluegills and bass. I personally use a 9' 5 weight rod, with a wf-f line. I use a 5x leader when fishing dries, nymphs, and terrestrials. For streamers, I go with a 3x. My fly selection is generally fairly small for Farm ponds. here are some of the patters that I use.

Bluegills
Hares ear nymph. sizes 10 - 16
Small popping bugs.
Small floating foam spiders and ants.
A small grasshopper pattern
A small cricket pattern.
A few generic dry flies- including Adams, size 12 - 14, Goddard caddis size 12
(can you say unsinkable?)
A few size 10 - 12 wooly bugger patters.
And if im getting short strikes, I switch to a 10 - 12 wooly worm pattern.
And lastly a San Jaun worm.

Bass
All of the above flies will take smaller bass and the occasionally nice bass.
Deer hair mouse (size 6)
Deer hair poppers
Popping bugs.
Crayfish patterns if you' re fishing for smallies.
A generic minnow imitation.
size 6 - 10 White,brown,black,olive wooly buggers (VERSITLE PATTERN!)
and a few muddler minnows.

Hope this helps. This should be enough to fill your first flybox
