[SOLVED] Moving the page menu bar a bit lower

Hi!
I hope you could help me, I'm such a newbie...sorry if my questions are so silly.
My problem is that I would like to move my pages menubar just a little bit lower, right above my posts. My blog currently looks like this: header-pages menu bar-space-posts and I'd like to delete that little space between my bar and my posts. I hope I'm making myself clear The thing is, I have no idea where to set that option, could you help me with that?

Also, I would like to know how exaclty can I set up the drop-down effect for my menu bar. Basically, I'd like to make a drop-down blogroll, if that's possible.

Ohh, one more thing: I cannot get the search box to show in my pages menu bar! I've selected the option 'Show search box?' to 'Yes' but nothing happens...why is this?


I appreciate your help.
