If you're still using Snow Leopard, then you can have both of them installed at once, but you must install them into separate places and use the xcode-select command line tool to switch between them.

You have to use xcode-select to switch to the directory tree containing Xcode 3.

That is correct; LLVM-GCC is just a front-end for LLVM that accepts GCC-style command line options. I've never had any major problems with either LLVM or the old GCC. What problems were you having, exactly? Compilers are among the most heavily QA'd products in the marketplace, so actual compiler bugs are quite rare.
