Using Html Codes

I have changed my template to iTheme2
With my previous template I had on the tool bar drop downs to change text colour, size and font style.
I don’t have this now?
I also used Quakit Html codes on previous template for marquees and other things but when I try now the code shows on the image page rather than just on the text page.

On another note – how do I remove the bit at bottom of page that show” Blog at WordPress.com iTheme 2″

Last query – Can I delete “Leave a reply” box from some of the pages.
