Lots of good info here for ya,may I suggest using honey worms either with long shank thin wire hooks,or coupled with a 1/32-1/16 jig.I know some say drop the float,but you are missing out on another dimension.When you mate a proper float with a small jig tipped with a plastic or natural morsel,your enjoyment level will surely rise,and your catch won’t suffer.
I like 2-4 lb test line,5’6 ultra light rod with a small spinning reel for all my bluegill fishing.I do like 7’ ultra light rods for casting for crappie,and 10’ - 12’ telescoping rods for dipping brush.Dont get too caught up in over buying ( that will come in due time ) Fish on !
