Here are some simple workbench/table plans using Simpson Strong-Tie system. I think the metal ties are available at most home improvement centers. They create solid work surfaces without alot work. All the cuts are straight and the plans come with both material & cut list. Here are a coupledocumments with tables, shelves and workbenche plans.

These may work well with the suggested previously suggested ceiling tile and cork work surfaces.
