which kit do I need

Honestly with the amount of miles on your stock rear i'd probably get this one Ford Racing M-4210-C - Ford Racing Ring and Pinion Installation Kits - summitracing.com, and it may not hurt to rubuild the t-lok. Seeing as how your motor has been freshly rebuilt, you might as well rebuild the rear so you don't end up blowing it up after the gear install due to worn out factory pieces and then you'll end up paying for labor twice to fix it.
 
That Ford Racing kit will be fine, I used the Ratech full bearing kit + axle bearings and seals and they are just fine.

Order an extra crush sleeve or two in case one gets damaged during the install. They are cheap and your installer will appreciate the gesture.

Go ahead and get the trac-lok rebuild kit while your at it; its $45 and will save you from cracking the rear end open down the road when it starts to wear out.
