I can't really tell from the photos, but I am assuming you are saying your tires are leaning in from the top? or are they pointing in toward each other, or out away from each other. It doesn't really matter, these are all repairable
Its a simple matter of your alignment
You can take it to a shop, or you can do it yourself. If you do it yourself, you won't get it near as precise. Every alignment is a little different, its based on a lot of things. If I were you I'd take it to a shop the first time, and see if they can let you watch. You'll learn a lot and then you'll know first hand how to do it yourself. I don't have that part of my FSM so I can't tell you exactly what to do, as I have only done an alignment once, and I screwed it up royally
As for the clicking, is it only when you are in 4lo? and is it usually noticable under load? it sounds like you've picked a winner with the cv joint. Are the CV boots all torn up? is the mud and water and gravel and such in the boots? you may need new CVs.
