How easy is it to remove...
 

1 - Im fairly (well totally tbh) new to skinning and never on this game, i was wandering how easy it is to remove the bag buttons and menu buttons on the left as i have absolutely no need for them and there taking up my a lot of unnessecary screen space.

2 - Second how easy is it (and how would i do it) to simply remove the graphics from the bottom bar just leaving the combat button and the bars?

You probably want Joviex's Invis Bottom Bar: http://www.lotrointerface.com/downloads/info3.html
