OK a Lil Help here....

I Bought a Dana 60 this summer... put it in the Garage till I had time this winter....( lemme first say I'm a noob here, an here too learn) and I knew it had some Obvious problems.... Bent Spring holders and Such but the most glaring was these Two issues.... The First Question I have is how does one Get the Knuckle Off to replace it, and Second.. where would I Get another... the Second picture is what I'm assuming is the steering control arm... to me it looks like I have to take the ring clamp off and simply bolt on to where ever it goes when i'm ready to attach it... BUT the Rubber Gasket is SHOT..... so I'm looking at replacing it... Correct?!
