Errors on installing my theme

I have installed WordPress using fantastico and everything was fine then i installed a theme called Blues using direct upload feature in admin page (I havent editied any file in that theme pack) This is the my page:- http://everythingforfun.x10.mx/

I got the following errors:-

Warning: Cannot modify header information – headers already sent by (output started at /home/gautham2/public_html/wp-content/themes/blues-wordpress-theme/wordpress-blue/functions.php:2) in /home/gautham2/public_html/wp-includes/functions.php on line 851

Warning: Cannot modify header information – headers already sent by (output started at /home/gautham2/public_html/wp-content/themes/blues-wordpress-theme/wordpress-blue/functions.php:2) in /home/gautham2/public_html/wp-includes/functions.php on line 852

Then i ignored those errors and installed a plugin named TDO forms for my 3.2.1 wp version, then i got some errors and on homepage i get these erros

OMF ERROR: Headers have already been sent in file /home/gautham2/public_html/wp-content/themes/blues-wordpress-theme/wordpress-blue/functions.php on line 2 before session_start() could be called. This may be due to…
Your current wordpress theme inserting HTML before calling the template tag “get_header”. This may be as simple as a blank new line. You can confirm this by using the default or classic WordPress theme and seeing if this error appears. You can also check your theme where it calls “get_header”.

And…With TDO mini forms anyone can post right? I want that feature so i cant uninstall that plugin coz its very useful
