when i first started blogging, there were so many little details to my blog that i had no clue i was able to control. the navi bar, for example. i'd always hated it, but i didn't really know what it was or that it could be removed. after a couple weeks i came across it in my layout and was like whaaaa?!
this is the easiest thing ever...
>> go to your blogger layout. you'll see the NAVBAR box, upper right. click edit.
>> click OFF.
>> hit SAVE and you're done!
but if you have any questions, let me know!
