Assuming by close buttons etc, you mean the ones on the titlebar -- the 
window decorations, that's a function of the window decorations, as set 
in kde system settings, workspace appearance and behavior, workspace 
appearance, window decorations.

You can choose between different decorations (with more downloadable from 
kdelook using the get new decorations button if you don't like what's 
there) for general appearance, and then depending on the decoration 
chosen, hit the configure decoration... button.  The available settings 
in that dialog very much depend on what decoration you're running, with 
the default oxygen decoration having a whole set of configuration 
options, while that dialog's pretty bare by comparison with some of the 

At least on the default oxygen decoration, on the general tab you can 
configure both border size and button size independently, along with a 
whole host of other options on the other tabs (and there's a whole 
additional tab, animations, plus a couple options on the other tabs, 
available if advanced is selected).

The scrollbar (and other non-window-decoration general kde UI elements) 
are configured in a different kcontrol module, still in kde system 
settings, under common appearance and behavior, application appearance, 
style, applications tab.  Again the default oxygen style is far more 
configurable than the others, and you can set scrollbars width on its 
configure dialog scrollbars tab.

While still in the style module, take a look at the fine tuning tab.  You 
may want to experiment a bit with the graphical effects dropdown.  
However, while I remember discovering at least one thing it does affect 
at some point (I believe after someone hinted at it in a post here), I 
don't remember what it was, and the effect is subtle enough it was hard 
for me to figure out what difference it made even when I was looking for 
it, on my own.
