You would need to take the tranny or motor out, motor is more fun. Then you can do all the gaskets with ease. Tranny is easier. I think?

According to my service manual, which is the OEM Factory manual for an 89 Brougham, you do need to lift the engine, to remove the oil pan. The books also says that if the upper rear main seal is being replaced, the crank shaft must be removed.
So you would need an engine hoist and a car jack with a set of jack stands. If you do not have a hoist or car jack, or any of the other necessary tools, and especially the hands on experience needed to do this job, then I recommend that you take the car to a reputable garage.
If you do decide to do this job yourself, then I highly suggest that you purchase a Factory Service Manual. Here are a few on eBay. (http://shop.ebay.com/items/_W0QQ_nkwZ1989Q20CadillacQ20broughamQ20serviceQ20m anualQQ_armrsZ1QQ_fromZR40QQ_mdoZ)
