MacTeX-2008 will create a new directory structure /usr/local/texlive/ 
2008, and install everything there (plus applications and ReadMe files  
inside /Applications, and -- if you decide to use the GUI for the new  
TeX Live Manager -- Perl/Tk inside /Library/Perl and /usr/local/bin).

The rest of the answer depends upon whether you're currently using  
MacTeX-2007 or gwTeX:

- MacTeX-2007 installs inside /usr/local/texlive/2007 and creates a  
folder /usr/local/texlive/texmf-local for your local additions. This  
latter folder takes precedence, in the sense that /usr/local/texlive/ 
texmf-local is searched before /usr/local/texlive/<year>/texmf-dist.
Now, when you compile XeTeX from source, if I'm not mistaken the  
binaries are installed inside /usr/local/texlive/2007 and other files  
(LaTeX packages, formats etc.) inside /usr/local/texlive/texmf-local.  
Hence, when later you'll install MacTeX-2008, it's advisable to erase  
all XeTeX-related components from /usr/local/texlive/texmf-local to  
avoid them interfering with those in MacTeX-2008.

- gwTeX installs inside /usr/local/gwTeX and creates folders /usr/ 
local/gwTeX/texmf.pkgs for local additions and /usr/local/ 
gwTeX.texmf.local for TeX admin overrides (formats etc.). I don't  
remember in which of the two XeTeX is installed when compiled from  
source.

In any case, given you seem to be using gwTeX currently, a later  
install of MacTeX-2008 will be completely unaffected by anything  
you've installed for gwTeX. Just make sure, after installing  
MacTeX-2008, to select TeXLive-2008 in the TeX Distribution system  
pref panel.
