Need some guidance. Limited on funds but some urgent repairs are needed for my 3.5L TF. I need to change out my engine mints and drive shafts but unsure what to do first. Or I could just put the money away, keep going and get it all done at once... Thoughts

Well you either have the money to fix the car or you dont. Both problems are relatively minor but may lead to bigger problems if left for a long time. Bad mounts will allow the engine and transmission to shunt excessively and bad driveshafts may fail completely depending on whats wrong with them.
