Windows 7: Optimal monitor height? Computer remote? Battery solution?

Update- All is fine with the setup except the monitor. Believe it or not, I actually plan to return my Dell 24" u2412 for a 23" u2312 even though with paying return shipping, the deal, etc., it even comes out to the same price! The issues are I lean in to look at my screen to see the text and I'm not happy with the height issue still (can't adjust desk/chair anymore/swivel arm) so I'm thinking the 1" lower height and the 1080 resolution (vs 1200 on the 24") will be more comfortable. I realize I lose 1" of screen space and a little more with the resolution and since I'm usually on the internet/office 1200 should actually be better. Anyone with advice in regards to what I am about to do?
