At the very least, I think you should use `tlmgr arch remove`, but then
you will still have a stale option in the preference pane (if you used

At present, on Snow Leopard (Mac OS X 10.6), you get universal-darwin 
and x86_64-darwin binaries.  The x86_64-darwin binaries will /only/ work
on 10.6.  On 10.5 and earlier OS releases, MacTeX installs only the 
universal-darwin arch.

If you think you need finer-grained control, you can use the install-tl
script to install TeX Live yourself, but any /usr/texbin path setup will
not work correctly.

I may add arch add/remove functionality to TeX Live Utility at some
point.  Correctly handling /usr/texbin is the main reason I haven't made
time to do that yet.
