Accessories for the 301 are pretty easy to find on Ebay - $15-$35 depending on how nice the box is. Manuals aren't hard to fine either. I've bought two 301's that didn't come with any accessories, though one came with a manual.
Bobbins are the same as the FW uses, but as Caroline said, it is a slant shank machine so the other feet won't fit.
When you say "table" so you mean a folding table or that it came with a cabinet? Either is a good deal, but if it came with the folding table then you got a steal of a deal!
