How do you safely UNinstall "Music Lab RealGuitar2 from a Mac (garageband)

I have a Power PC MAC running 10.4.11 Tiger and I have 2 plug ins

in Garageband that I want to UNinstall: Music Lab RealGuitar2

and RealStrat. I don't really need them anymore. I only started with 233.64 GB

of space. Now I have 128.93 free. I've been cleaning up files to get more memory

and these plug-ins (or AU's?) have to go. I'd like to just drag the apps to the trash

but online advice says "download a pro-uninstaller to do the job or the computer could act very

strangely if the apps are trashed manually." There is more than just one icon per app with these

plug ins - ie, bundles, engines, components etc. I'd love to just throw them all in the trash and move on

without screwing up my computer but life could never be that easy, right? Thanks in advance for

any helpful info. I'll be getting a new Mac soon but I have to squeeze out a few more songs from my

present setup before I make that jump.
