x2 on the spindles. When shopping around make sure you get ones specifically stated "EDGE/SPORT" since the torsion bar ones are different than the coil spring ones (upper ball joint is bigger on torsion trucks). I'd hate for you to mistakenly pick up the wrong ones. This is the kit I used on my Edge -->

As Tyler stated, the Maxtrac ones are the same thing. Both are a good purchase.
As for torsion keys, I'd pass. While cranking your bars up to 2" (for free, alignment recommended) keeps you within factory specifications. The 3" lift keys take you out of that range and allow you to exceed this even further. You may have issues with your upper A arms and your ball joints will wear prematurely. 4wd guys also have issues with CV axle angles as well but that does not pertain to your truck.
For the rear, as stated above you already have a 2.25" lift block from the factory. The lift shackle in the link above will give you 2" in the rear and in my opinion is easier to install than a AAL (add a leaf). Both options work well and can be used together. No need to go fancy on the AAL, paid $40 for mine new and have not had any problems. Replacing your U bolts is recommended as well (rockauto has them for a good price). With the 4" spindle and 2" shackle the truck will be slightly higher in the front. If that is not the look you are going for, the inclusion of a AAL in the rear brings things back to the factory rake.
A body lift would be a good choice as well. The Performance Accessories kit and the Summit Racing kit are the same thing so either or will work. Installation is not bad, just time consuming. With the help of another member here we had mine on in about 8 hours or so which included a break for lunch. Typically I recommend spindles over a body lift for the sheer fact that spindles with raise the whole truck not just the body.
You mentioned tires for a 17" wheel....I presume the truck has aftermarket wheels on it? Just wanting to make sure since Rangers only came factory with 15's or 16's. As mentioned above, since you are looking at a 32"-33" tire your gear ratio is something that can come in to play. Edge's typically came with 3:73's or 4:10's. My 2wd Edge came with 3:73's and I would think most of the 2wd ones did. Seeing as how you are from FL I presume hills are few and far between. With 33's and 3:73's hills SUCK.
Picture time (for reference and whoring)
My truck with 33x10.5's with factory height. No clearance issues but was never driven off road. Spindles were installed the next weekend.
Same 33x10.5's with 4" spindle and 2"shackle.
Again, same 33x10.5's with 4" spindles, 2" shackle, 2" AAL, and 3" body lift.
35x12.5's on 8" wide wheels with 4" spindles, 2" shackle, 2" AAL, and 3" body lift.
35x12.5's on 10" wide wheels with 4" spindles, 2" shackle, 2" AAL, and 3" body lift.
At no time were my torsion bars cranked. For informational purposes, in the last pic the top of my cab is around 6' 4" tall.
Hope that helps.
EDIT: Forgot to list the body lift. Not sure if I have a pic with just spindles, shackles, and AAL.
