help with header??

here is a link to my gallery/phpbb2 integration. i need help editing the top navigation of the gallery. the part where it says "your album" "contact" "forum index" "gallery" etc... i can't seem to figure out the file to edit to change the text and stuff...like instead of saying "contact", make it say "send us a letter" or something. also i want to make where it says "forum index" to be more pronounced and have like a dash between that and "gallery" well i hope i explained myself good enough. thanks.
