I've never done it but I think oil pan removal is bit of a pain on these. I believe you can just raise the engine a few inches, with a hoist, or a jack from underneath or maybe a top engine support would work if it has a few inches of lifting capability. you'd need to undo the motor mounts, probably the exhaust at the manifolds and bracket at the trans as well as the trans mount. Careful of the shift linkage I suppose. Somebody who's done it would have to chime in to verify all that or give further advice on this procedure.

What's the problem with the plug? Is it buggered up, rusted?
I Think I'd give my best shot at liberating that plug before I'd replace the pan because of it. Maybe even drilling it out and using a big easy out.
