Yamaha DTXpress/DTXplorer/DTXtreme

Let me give you the before and after on my mission here.

I just bought a Pintech Zenbal single zone High Hat to replace the 
TP65 Yamaha pad that came with the set (I didn't like the unnatural 
feeling and shape of the TP65). I now want to use the TP65 as 
another Tom.  Currently, Input 9/10 is being used for another Crash 
cymbal I bought separately.  Hence, all of the inputs behing the 
module are populated.  Because the end result of this upgrade is 
that I've added one pad to my configuration, the only place it can 
plug into is the input jack on the KP kick pedal.  The instructions 
say to utilize that, a cable from the output on the KP MUST connect 
to Input 9/10 on the module.  To do this, I must now unplug the KP 
cable from Input 1 and move it to Input 9/10 to get that extra Tom 
working.  However, that also means I have to unplug the current 
crash cymbal in Input 9/10.  I still want to use that as well, but 
the only available Input now is Input 1 (the now-empty labeled Kick).

My questions are:

1.  How do I permanently "remap" Input 1 (labeled Kick) to now be a 
Crash Cymbal.  By permanent, I don't mean just creating my own kit 
and storing it as Kit #49 or #50.  I mean, if I chose to play kit 
type "Big Reverb" the crash cymbal would make a cymbal noise - not a 
bass drum noise that the module thinks is connected to it.  I'm sure 
there's a way to do a permanent remap - I just don't understand how 
to do it.

2.  I kind of know how to configure Input 9/10 now to be both a bass 
drum and a tom, but I have the same kind of question.  How do I 
permanently remap that configuration so if I chose to use a canned 
pre-set kit type, like Big Reverb or Rock Dry 2, the module will 
play a bass drum sound when I kick - not a Cymbal.

3.  My new Pintech high-hat is, out-of-the-box, very quiet and I 
have to hit it hard to get a decent sound out of it.  How do I 
manipulate that non-Yamaha cymbal to produce a nice heavy Hi-hat 
sound without having to swing hard at it.

4.  I'm also getting a fair-amount of cross talk when hitting the 
new hi-hat.  I'm hearing the newly added Tom (TP65) and the snare 
drum as well when striking the Hi-hat.  I think there are some 
rejection settings there that may work for this, but it's unclear.
