BBcode and Message box

Hi! I have a couple of questions.

How do I make it so that the bbcodes make a neat line on top?
The bbcode right now takes up a lot of space, how can I make it horizontal line not vertical?

How do I make the reply box above the messages?
How do I make it so the reply area is the first thing you see?

Thanks a lot! I appreciate any help!
