Sounds like you have low fuel supply or a leak in intake system causing lean codes, check fuek pressure and volume first. Cat converter effeciancy could be caused by the lean codes, purge system sounds like solenoid failure, check for high resistance accross purge vent solenoid.

A direct fit converter for your car is is available from Eastern Catalytic. However a reputable muffler shop should be able to install a threaded port for the 02 sensor if you want to go that route. Call around, get prices, and from that you can make a decision.
Hope this helps.
