A few questions about SOA, axles, diffs, and ring & pinion

[Dink]

Ok here's a few of the things I've been trying to research and learn about, and as always if I missed the thread already dealing with this topic please refer me. I'm trying to decide the route I would like to go to lift my Jeep from what I've already read SOA is harder but worth the effort in the long run. If I'm going to begin collecting parts for my SOA, would it be wise to start looking for bigger beefier axles, like a Dana 60 with flat top knuckles already on it, or just buy Tad's knuckles and his parts to SOA my Jeep as it already is? Is it worth looking for a wider axle that I already have? Would it be smarter to just modify my AMC 20 rear and Dana 44 front? I only ask because I noticed RiverBeast has Dana 44s front and rear if I remember correctly and his Jeep is pretty modified. Also if I'm going to be using it as primarily off road with on road just to get to the trails should I look for possibly different ratio ring and pinion?Great Googley MoogleyAs of right now I'm contemplating doing a full spool up front and a locker in the rear, any advice on that setup? This vehicle is my toy I have a bike and a truck to get to work and drive daily so this thing can be a little on the modified side not super extreme but I would like to have a little more modified than most. I know this is a lot of questions but I'm really trying to make the most informed decisions I can, because in my current amount of research I've read quite a few FSJ owners saying they wish they would've just done and SOA first and not wasted their time and money on other lifts, so I'm trying to use the "collective wisdom" of this forum as someone put it, to learn from.
