When uploading the OpenWRT firmware via tftp, is it necessary to rename the image to
something special or how does the bootloader know where to find it? Does it just try to
boot the first file it finds?

If I'm not mistaken, the name doesn't matter at all.
The TFTP server that accepts your firmware image REPLACES the contents of the current firmware. Since it's in charge of processing the downloaded file, it puts it in the proper spot to boot from it from then on.

The firmware image is a self-contained filesystem compressed using squashfs. I'm hazy on the exact details, but discussions on mounting/reading/modifying the original linksys firmware can provide some insight.

There are numerous details scattered everywhere through the wiki. ALL of them are helpful, so you may just want to read all of them..

Hope I didn't give you too much homework. 
The discussion might have continued from here.
