well, i wouldn´t move them downwards tbh, because then one would only be able to see 1 circle of the three. you could move them to the left though, and the posts and sidebar and pagination along with it.
entries = posts
sidebar and pagination is clear I guess
rightcolumn are the circles
move all those thingies about 50px I´d say, so for example:
entries: 425px, sidebar: 10px, pagination: 80px, rightcolumn: 1100px
the lower the number, the more it moves to the left
the higher the number the more it´ll move to the right.
if you really want to move the circular images sidebar downwards, then change the number of “margin-top” to something higher than 0.
remember to move pagination and sidebar always with the same amount of pixles, if you don´t it will look kinda messy.
I added the description thingie because I forgot to change that in the new version of this theme, it´ll look better with the other font.
