First, the weather was not specified, the time of the infraction was not specified, and the traffic information was not specified.
The time, weather, and traffic volume info will be on the NOI that this statement incorporates. If the weather and traffic volume were omitted on the NOI, it will be viewed as a harmless error anyway. If the time of the violation is missing from the NOI, you may have something…not sure.

Second, two officers signed this one affidavit. That makes me wonder which one actually did the LIDARing, which one is actually the qualified/trained operator, etc.
This could well be an issue. I suspect that one signature is a training officer and the other a trainee. Nonetheless, either both officers should have written a statement or the training officer should be identified as simply supervising the trainee – in other words, trainee signs the statement as true and accurate and training officer signs as having reviewed the statement (or similar wording). The way it is, you are correct. It is unclear who tested the LIDAR, who used it, etc. And, most importantly, it is unclear who’s statement it is.

These things are probably pretty minor, however, but this next one seems more important.

Third, the speed limit on MP 58 is actually 55mph. MP 59 is 45mph. He probably LIDARed me in between these two spots and that's why he gave me the ticket. However, I think this is important because the affidavit says that "The defendant's vehicle was traveling westbound on SR 20 MP 58 In the left lane." Additionally, he says that "At the time of the measurement of speed, my vehicle was located at SR 20 MP 58." He does not make any mention of where my vehicle was at the moment my speed was measured. If he had specified that my speed was measured when I was traveling in MP 59, then the cause to give me an infraction would be correct (theoretically). However, because he only mentions MP 58, where the posted speed limit is 55mph, then technically I was only traveling one mile over the speed limit.
This is probably not going to as much use as you believe. If the MP 59, 45 MPH zone is east of where the cop was parked (at MP 58), which (unless I’m having a senior moment) it is, it’s not going to help you. The speed limit remains 45 until you PASS the 55 MPH limit sign.

One last thing that's probably minor: he measured my speed at a distance greater than what he calibrated the SMD at. Is this a problem?
Nope, not a problem (for the cop) at all. LIDARS are tested on a “known distance” course – at targets positioned at a known distance. If the LIDAR is found to be accurate at two known distances, it is accepted as accurate at any distance within its design range.
