The wood will last for years in the tank. they just rasp at it like sandpaper. Eventually it will get worn away, but it takes ages. Type isn't that important, any of the ones sold for aquarium use will be OK. You can collect your own, but knowing a bit about trees and wood is a pluss there. Some types of wood will leach sap into the tank and cause problems. If you dont know, buy a lump from the pet shop.
Plecos will rasp over any surface, wood, glass, rocks, plastics ornaments etc and scrape off the algae and micro-organsims that may be living on it. They wont harm a glass tank, but some of the bigger ones can mark a perspex tank.
They like those ceramic 'hollow log' ornaments as a hiding place. Set it up so you can see inside, the plec will sit in there and watch the world go by, and at least you can see it.
Filter type... get a good one one.. Plecos are Poop machines
I use a thin layer (1/2") of fine gravel in my tanks just because it looks better than bare glass. With a thin layer you can work it over with the gravel vac and keep it fairly clean. See the poop machine comment above
