[SOLVED] Need help with a few tweaks in Atahualpa

Hi there,

Yesterday on my website (http://clubpenguinmemories.com/) I installed the Atahualpa theme, and as you can see I've customized it quite a bit.

However, there is a few things I can't seem to figure out. I've tried Googling it, but I can't see I've found an answer. Here's what I need help on:

• Navbar is all weird. I followed this thread and it worked great, I reverted the changes, put them back again, and now it's staying. :/ I want the side arrows removed too - how can I do that?
  

Thank you so much. I know it's quite a bit, however I'm pretty nooby with CSS and figuring out where to put these things. Any help with this is greatly appreciated.

Devin
