Here are the addresses I've found:
6955: X pixel position
6956: Y pixel position
000E: In-game timer, decides when you can press A to close text boxes and when you will move.
Here's a quick guide on how to watch RAM addresses:
1. Open up Memory Watch.
2. Under "Adresses", type in the addresses you want to watch (a hexadecimal number between 0000 and FFFF). Next to the address, under "Name", write down what you want to call this address. You can call it whatever you want, it doesn't really matter. Under value, you can see the value for this address. After entering the values, you should save the file so you don't have to re-enter them every time you load the emulator.
If all goes well, it should look like this:

If I move a little to the right, it will look like this:

Notice that my X pixel position increased from 62 to 84. This means that I've moved 22 pixels to the right between the two pictures.
The Y pixel position works in the same way, if you move down, the value will increase.
I haven't completely figured out how the in-game timer works, besides that your character will move when it's 0. I might look into this some more later...
Anyway, by looking at your X and Y position while TASing the game, it will be a lot easier to position yourself optimally before entering a new area. Good luck!
