Touch Pro Help

[emd2009]

Hey! I recently upgraded my Treo 800w after coming from the Treo 700wx to the Sprint HTC Touch Pro, and I love it! I have installed MightyMike's Rom and the newest Sprint Radio. However, I want some help on these things:

1. In the Text Messaging App in Outlook, how can i Change the left soft key from "Reply" to "New"

2. There is a terrible typing lag when using the hardware keyboard.

3. I want to change the default MightyMike theme to the one from Alltel, how?

4. I wanna change the brightness on the fly, could i map it to the long press end key?

That's all for now!
