upgraded to wm 6.5, need help w/ some old features

I've been using the HTC TP2 for a while with Mobile 6.1 and previously I used the HTC Touch also with 6.1, I believe. I just updated to 6.5 yesterday and I've been having problems left and right and was wondering if anyone can help me. I've already had crash errors and it has only been a day. Aside from that, I have some functionality questions.

1. I used to be able to set my phone to be able to lock by holding down the end button. I can't seem to find the feature now. Does anyone know where is it?

2. I cannot set up my email account for Hotmail. It would open up Opera so I don't get any notification on new emails. How do I set it so it goes with the emails

3. There was a setting to put the time on the top right corner. Has that been removed on this version?

4. For some reason I cannot set up my work pop mail. I got incoming to work. I entered smtp.bizmail.yahoo.com for the outgoing and it is not working.

Any help would be greatly appreciated.
