After many many times of changing a font package or brightness fix, or whatever to "Update.zip" and moving it to the root of the SD card, I actually took the time to look at the other items on the ClockworkMod Recovery console. Specifically the one that says "install zip from sdcard". You select it, and on the next menu choose "choose zip from sdcard" and it brings you to the folder list of your SD card. Simply find the file you want to flash and select it. Huge time saver. Maybe I missed that in the thread I used to root, but thought I'd share the tip for those that didn't know.
