Answer 1

Have a look at this apply the following style or change the value for "left" if you want
#cssmenu ul ul > li:hover > ul {
left: -50px; **Change this to whatever you want to**
opacity: 1;
visibility: visible;
}
^ this is on line number 105 of your CSS stylesheet.
Hope this helps! Let me know how it goes :)
UPDATE:-
Change this as well
#cssmenu ul ul ul {
left: -50px; /* Change this to whatever value you used for the above "left" attribute */
This should fix the strange transition issue.

Answer 2

Cant you manually position the sub menu?
Just add a class to the sub menu, and
subnav { position: absolute; top:10;left:10; }?
