Your inner body panels dont look to bad but it is hard to se behind where he crossmember is bolted on.Check it carefully in this area. I have included a picture of the rust damage / patch.
Removing the crossmember is a huge job (spot welded / welded to floor pan) and I would not suggest it unless you have major rust issues. I would be interested if anyone has ever fabricated the inner body pieces since I will need to do this. Hope this helps.

Rust always has a larger surface area than visually seen.
