An alternative is the Mac's built in Startup Manager.
http://support.apple.com/kb/ht1310

but it requires you to hold the option key at startup, and only allows one legacy OS (Windows/Linux) per hard disk. Additional legacy OS's on the same hard disk would require a chain loading option be added to the Windows Boot Manager (look up EasyBCD at http://neosmart.net/dl.php?id=1\) or Grub2. But those BIOS based boot loaders don't support booting Mac OS X very well.

To configure rEFIt, edit the /efi/refit/refit.conf file.
http://refit.sourceforge.net/doc/c3s2_access.html
http://refit.sourceforge.net/doc/c3s3_config.html

If there is something that you want to remove from rEFIt that is not mentioned in the .conf file, then you'll need to download the source, make changes to the source, and recompile. I believe you can do that with free Microsoft development tools with some minor modifications. The build instructions are in the source code.
