Do all plecos need wood in their diet? What kind can I use?

Some plecos do.
The easiest is to go to a fishstore and get some kind of driftwood. This way you're getting something that is good for your tank (not likely to have extra toxins, parasites, other things that can hitch-hike in stuff you find in nature)

does the pleco I have need wood?

If you mean the "rubber lip" pleco in your aquarium info, probably not. If "rubber lip" is the same as "rubbernose", then no.

The above links are profiles to three closely-related plecos that all fall under the "rubbernose" common name, and all three are listed as omnivores with no mention of needing wood in their diet.
