Mac Mail questions

I have several questions, and rather than make a bunch of posts, I figured I'd compile them all in one, and if anyone can answer any or all of these, that would be amazing.

1. When I create a .pdf, if I copy the text from there then paste it in Mac Mail, it saves it as an image type file that I can't edit. However, it does not do this on Entourage. Any idea how to fix this? Basically, I use different fonts in my pdf's but what to be able to send the actual text to people in a normal font, but it won't let me.

2. Is there a way to get buttons on the Toolbar to Bold, Italicize, and Underline text when I open up a New Message without having to either use the key commands or open up the Font tab? Think like the buttons they have in Office.

3. With Entourage, there is a setting that will bring a little pop-up notification in the lower right hand corner to let you know when you have a new e-mail. Is there a way to do this with Mac Mail?

4. When I attach picture files like .jpg and .png, is imbeds them in the e-mail instead of saving it as an attachment. However, if I atach a .doc or .docx or .xls, is saved it as an attachment. How do I change this so my pics will default as an attachement?

Thanks again everyone for any and all help.
