Help! Got Problems Help!

I should have posted this is my previous topic but i only remembered after i posted lol.
Q1: why does word press add extra line breaks in my entries, even if there isnt a line break?
https://deliciouz.org/!/x/ – there isnt a line break between the entry title (Theres only meant to be a few spaces) or the entry and my name (theres only meant to be 2 line breaks), and yet wordpress has made it have huge gaps that i dont like. lol. – this is also the case for comments how would i sort both these problems out?
Q2: how can i display clickable smilies on my edit page? is it possible?
Q3:how can i display clickable smilies on comments popup as a popup?
