Newer vac pumps vent into the crankcase instead of into the intake, so just plug the line at the intake.

Broken seat should be an easy fix, just pull the one from the parts car. You can change the covers fairly easily if you want, also.

Rust needs to be taken care of pronto, at least scrape all the paint and rust off, patch with fiberglass if necessary, and use some etch or conversion primer, then touchup paint. Probably look sloppy, but better than letting the rust eat the car!

Water on the front floor is from a leak, windshield or plugged/rusted out drain at the hood hinge area. Pop the hood, open it all the way, and check the drain. You may also need to crawl under the dash and check for rustout there. If rusted, patch with fiberglass, etc to keep the water out, or the floorpan will be next....
