For me at least, panfish is tough on this lake because anything you catch is so small it's not worth keeping. Small sunfish about 6-8" long are the usually cricket and worm grabber. You also have to get the bait up close and personal with any cover. They won't venture out away from safety to take a bite. You have to make accurate casts to cover (within a few feet) and as soon as the bobber hits the water its a matter of seconds before you need to get them away from cover to prevent them from hanging your hook in the cover. It's for an experienced angler, not for kids.
For crappie, they typically roam around and suspend on flats. Trolling works best unless you venture past the Hwy 12 bridge and go way up river. Since you're on the opposite end of the lake, that's not really an option. For whites, look for them on main lake points near the Rocky Branch area as stated above. A white or silver Rooster Tail works great when they are schooling and it's a "do nothing" type bait. Cast as far as you can, steady retrieve. It helps if you twitch it a bit every few turns of the handle.
Good luck and enjoy your visit to Beaver!
