You don't flash it in CWM. It is a tar file 7 zipped. You unzip it with 7zip or winrar, which will give you a tar.md5 file which you flash through the PDA section of ODIN.
Glad you figured it out. If you have any questions about flashing through ODIN or CWM, you can click the link in my signature for DroidXcon's great guide. It contains screenshot visual aides, and even though it is designed to help people understand how to flash things through CWM it does include basics for ODIN. As always, if you have any questions don't hesitate to ask. Android Central is a place for learning and sharing information about Android phones.
Thx Landshark. I was just a little confused that someone had recommended downloading the TBH app and get the ROM from there. I am more comfortable with ODIN though so it all worked out. You guys are an indispensible(sp?) source of info. I really appreciate it.
