Currently there are no hooks for these things, but it could happen  
through a plugin. Something which is soon to debut -- are you  
familiar with writing Objective-C? if so, I'd suggest subscribing to  
textmate-plugins [1] (and there should soon be the required  
notifications by means of a plugin).

If your command launches a new process, that process will continue to  
run after control is returned to TextMate.

If you want to provide an interface to control the process then you  
can make use of the ability for JavaScript in the HTML output to  
control shell commands. I added an example command to the  
experimental bundle [2] which opens a window with the time (updated  
each second) that you can start/stop.

No, that's currently not possible, but as implied above, I don't mind  
providing the necessary notifications (as NSNotification's that an  
Objective-C plugin can observe).
