Push internet + Kill Opera help

[boldaslove]

1. I had installed the No Push Internet.cab before, but silly me I couldn't get internet access "restarted" again afterward. Settings > Communication > Direct Push didn't do it. (I use wi-fi only with no data plan and normally don't access net on the phone so I'd like it disabled by default but of course in case I do need it, turn 'er back on.) How would I get the net going if I install that .cab?

2. How do I get rid of Opera from still running after I close it? I have tried a couple registry tweaks like:

HKCU\Software\HTC\TaskManager\TerminateProcess\

and setting "Opera9.exe" to "1". I even run Advanced Task Manager and hit Terminate, but the sucker won't die!
