First of all...congrats on your nuptials...and on still being allowed to do RC!

Now...for the REALLY important stuff. *heheh*

First, allow me to STRONGLY recommend [link=http://www.amazon.com/Stick-Rudder-Explanation-Art-Flying/dp/0070362408]Stick and Rudder: An Explanation of the Art of Flying[/link] by Wolfgang Langewiesche. It's THE bible for pilots. Written BY a pilot, FOR pilots, it's not full of a bunch of engineering babble. It is, essentially, the best primer on how and why airplanes do what they do ever written. Yes, it's old...but hey, the laws of physics haven't changed. *heh* When a pilot (RC or scale) starts asking the sorts of questions you've asked, then it's time to dive into S&R, imo.

Among other things, it'll teach you why dufault is wrong when he says "In a crosswing you need to apply alot of rudder". CAN you fly a crosswind approach in an uncoordinated slip? Sure. SHOULD you? Depends on a host of factors, not the least of which simply being personal preference.

It'll also teach you why airplanes slip and skid...and how to use the rudder to avoid it....and when you should...and why.

It'll even teach you why the rudder doesn't turn the airplane...despite the fact that you've owned an airplane that only had a rudder for turning.

===========

Mastering the rudder is, imo, a MAJOR step between good pilots and excellent pilots...either in full scale or RC. Your airplane has 3 axes of rotation...ignoring the rudder is the same as ignoring 1/3 of the control you have over your airplane. Can you herd an object around the sky with only 2/3 of the control surfaces? Sure. Will your flying be greatly improved if you master all 3? Absolutely.
