You've got to have a vent. If air admittance valves (Studor vent) are permitted by your code, that sounds like a pretty good solution if it is not practical to run a real vent. Once the tub drain is vented, you can tie it into that 4" drain line.
When you remove the existing drum trap, cap or plug the line coming up out of the floor--who knows if it's connected to the building drain or not, but you don't want sewer gas coming up into the basement from an open hole in the line.
