'nother question- does the area ID determine wether Link swims or walks in a map? And is putting warps underwater the same as putting them in regular doors/stairs?

Yes. There are bit flags and one of the values controls if it's an underwater area. You can't change them through ZOLE, so you'll have to work with existing ones or hex edit them by yourself (They're in the area headers). For underwater warps, yes, unless you mean diving up. Then I'm not sure.

How would you go around editing the title screen with TLP? Do you need to do something in ZOLE first? If not, I can't figure out how to get TLP to display Ages tiles correctly. I can recognize some tiles, such as the Seeds. Maybe I need to edit the pallet?

The graphics for the title screen are compressed. You can't edit them unless you compress the graphics and re-insert them.

 How would I decompress them, then?

What type of program do you use to look at ASM? A Hex Editor?

No, typically BGB's debugger.

I see... The debug window looks very confusing.

I'll write a tutorial one day. In the mean time, you can use this for help (Very useful):

Mainly look at the opcode listings, like CP n.

Gah!  I finally got something done, and when I went into the game to survey the land I'd created, I found this. ZOLE shows the correct tiles. Any tips? Also, a group of four tiles render as completely black, and Link suddenly obtained the L-3 Sword out of thin air.

I'm not sure. I noticed that a lot of times in-game, going into the area with the guy who gives the island map will mess up the tileset sometimes. I'm not sure why. I guess either change the area id if you can, and if not, then make sure to try it without save states.

I was able to counteract the anomoly in the picture by making it a new ledge, but I'm still working on the black tile problem; changing the area I.D. doesn't seem to have any effect.

If the cliff edges are randomly placed there, then it has to do with some table of data that places tiles that ZOLE doesn't edit yet.

They look like they're for something like stairs or a waterfall. Here's the other error I see:
