BEST SETUP FOR RIVER FISHING

I am new back to fishing and have spent the last few months at
fisheries doing a bit of Carp etc and now that the rivers are open i
have decided to go back to trying my hand at a bit of river fishing.

The river (the AVON at Lords Walk, Amesbury, Wiltshire) i am using is
not too fast flowing but very weedy - i know its got trout and grayling
(and apparently chub too) in but want some advice on the best setup and
bait to use nowadays on the river???

Any advice and help would be most appreciated.
