Can't send an email and don't get any errors....

New to the UE extension (just got it hours ago) and tried following the getting started guide. I also watched the video and followed along.

One question is that in the video it references getting some code based on the model being used. In my case, I'm using PHP. Where is this information obtained? In the video it appears to be some place that is not part of the UE behavior although everything prior to that page shown on the video was interaction with the UE behavior window.

Another question is around the plain text view of the body. Can the HTML preview (from the Body tab) have something completely different than the text tab? I tried inserting the php code shown on the video in the text tab's view after clicking edit, and the code appears there OK. I typed some random text in the HTML tab view to see if it would show up in an email.

Another question around using the PEAR module for mail. It asks for the path to the PEAR module which in my case is found within the PHP directory that's contained in WAMP's www folder. Is there a specific directory in the PEAR directory I should be pointing to or just use the PEAR root directory?

And finally, I saved all my work after creating a simple form based on the getting started guide, previewed the page in Firefox, entered some info including a legitimate email address and clicked submit. If it did anything, I can't tell because I saw no failure notice or anything else pop up to indicate mail was sent. I had it redirect to a page after clicking submit and that worked, but no mail ever shows up. Problem is that I don't know if it ever sent it or not. How or where would I look to see if the email was actually sent or an error was encountered?

I entered the SMTP info and port per my current ISP's setting to test the page. I tried both the email selection as well as the PEAR selection and couldn't tell if anything happened other than I've never gotten an email.
