FYI, your engine is supposed to idle around ~800RPM. If it idles at 1500 you've got something wrong somewhere, like a vacuum leak.

As for the acceleration problems and shaking: Motor mounts aren't going to affect your idle speed. Check your coil packs, pull them off one at a time and see if pulling one of them doesn't affect the way the engine's running. If you find that, use a timing light to see if the coil is getting spark.

Have you ever checked the timing on your motor?

yeah check your timing supposed to be 16*, look for boost leaks, your motor mounts are probably shot as well, as with most of the sr's rocking the stock mounts i've seen.

yeah check for vaccuum leak... ie intercooler piping
