This worked great for replacing the background in one of my levels. However, I'm now trying to insert a background in another level and I'm constantly getting the "not enough available 8x8 tiles" message, even with very simple backgrounds. This happens even when trying to start inserting at page 100 or lower. Is there something I'm doing wrong or a way to work around this, or is the insertion really limited to ~1 custom BG per rom?

Definitely not; it must be something you've overlooked.
One thing you should be doing is checking in the "Convert and Paste Bitmap" dialog for the number of tiles your image is using. Compare "optimized 8x8 tiles" (the size of what you're inserting) with "available 8x8 tiles" (the space you have) to see if you're just barely over the limit or if the values are looking implausible altogether.
Possible you're not setting up your GFX slots correctly? The slots you want your image to go in (probably BG1, BG2 and BG3, but your setup may vary) should have blank (or non-existant) ExGFX files assigned to them and look empty in the 8x8 editor. If you want to minimize the potential for mistakes, create blank ExGFX files by copying an existing file and erasing its contents in a tile editor, then use those.
