Yamaha DTXpress/DTXplorer/DTXtreme

I am finally going to upgrade my cymbals to a full set of Visulites:
ride, crash, and hi hats. But I have a few questions, and I apologize
if these have been asked before. I have the DTXPRESSII.

1) There are several versions of the Visulite hi hats. There is a
Yamaha specific one. Will it work 'as is' or do I need to make any
modifications or do anything weird with my DTX brain?

2) Do the hi hats require a hi hat stand?

3) Do the cymbals require a cymbal stand, or will they work with the
Yamaha mounts?

4) Are there Yamaha specific crash/rides that I need to look for? Are
they direct fit replacements for the DTX pie pieces?

5) Lastly, do I need to make any changes to the sound settings for
these new cymbals? 

Thanks for all the help!
