Archives in header

Hi, i started to use your Shutter Up Free template on my first portfolio page. It seems pretty cool, but i have one little problem. Header has a great options such as "custom header title" and text, which i was ready to use, but when i turn static page as my homepage, it's changing to display only "Archives" ("Archiwa" in polish). Is there any posibility to display custom texts in header on homepage when having static page set? And, also, now every subpage shows it name and date on the header, which is not necessary, as the title of the galery/entry/subpage appears below the header. My WIP page is http://michalkozera.pl/. Thanks for sharing great theme!
