You'll get much better replies from others with far more up to date local knowledge.
Many easy Avon routes (e.g. around the Sea Walls) are highly dangerous due to poor protection. There have been fatalities. Please take great care.
Would get at least two full sets of wires and another set of small wires (say Rock 1 to 4 sizes). And a couple of bigger hexes, just in case. Many Avon routes wander all over the place as the pioneers were (understandably) trying to find the lines of least resistance. But this means that generally you want double ropes. You also want lots of extenders. You may need to change your krabs over to longer quickdraws for trad. You also want some longer slings for even more extending (e.g. on traverses).
Route finding can be tricky.
Much in situ gear used to be highly suspect. But I believe a lot has been replaced? Others will confirm this (or not).
Suspension Bridge Buttress is a different type of rock, more like Peak limestone, in my view safer and easier to read. Some great HVS/E1 routes like Hell Gates, Earl of Perth, Limbo for you further down the line.
