Any Advice? Impending Transmission Installation Hassles

Hey guys, I bought my celica lets see.... a month ago now. I bought myself some new drive axels and installed those last night and next on my list is a new clutch and used transmission with lower miles. Its a 5 speed 2003 GT. Anything I should know other than the obvious pain in the but transmissions swaps that are specific to celicas? I figure someone on here has done this before. Thanks, much appreciated, hope you all are having a great friday.
