using a new font for headers

Hi, I'm new and a little frightened of CSS.

I would like to change the font in my post headers to a font not found in typekit. Is there a tutorial about how to do this that is easy enough for beginners to understand without screwing up my entire blog?? My first attempt failed miserably and I couldn't even gain access to my dashboard. Had to get in through the CSS in my hosting account to delete the one measly line of code I had put in. (Thankfully that fixed the problem.)

The font I'd like to install is Honey Script. Where can I find out how to do that?

Thanks in advance for helping a newbie.

p.s. Alternately, I could use images for my page buttons/tabs whatever you call them. I can easily create the look I want and save them into images, but would using those as page buttons be easier or harder than changing my post headers? I just need to switch up one of the two and I'm looking for the one I'm least likely to screw up with my limited experience. TIA for your suggestions/help.
