I think the name should go under the cab somewhere (in the white space), the design is more balanced that way. Also he had his name all lower case (cruiser54)
I have CoverKing ones in my MJs, fit well and really keeps the temp down. They roll up, not fold.

No, there should be two posts that sit in grommets in the frame crossmember. Those slots are for the fan shield on the passenger side or auxiliary fan on the driver side. This info is for the 4.0L, not sure of the 2.5L.
