Dayton Audio XO2W-2.5K 2-Way Speaker Crossover 2,500 Hz
Is this prebuilt?
Is this product pre-built when it is shipped to me, or do I have to solder the parts on when I get it?
Yes, it is pre-built, it is a highly-integrated unit consisting of the parts you see, the PCB, and a back-board that is hot-glued and riveted to the PCB.; you just bolt it to the cabinet and then plug it in. I don't own exactly this configuration, but one very similar to it.

Can I use these with ribbon tweeters??
Yes. You can use these with any 8ohm tweeter with the possible exception of piezos which would require an 8 ohm resistor across the outputs. You may need to pad the volume down to match the output of the woofer as ribbons usually have a higher spl at a given wattage.

What will the impedance be with both mid and tweeter at 8 ohm?
If I use both an 8 ohm tweeter and an 8 ohm woofer, what will be the load to the amp be
The amp would see an 8 ohm load.

Being a 12 dB/LR alignment, are the output terminals for the HF section pre-wired in reverse polarity, or will I need to reverse the polarity of the HF driver myself?
The tweeter polarity is reversed in the design. As long as you connect all "reds to red and blacks to black" everything will be acoustically in phase.

doing a MTM setup
Do I need 2 or 4 of these crossovers for a MTM build?4 - 8 ohm woofers, and 2 - 8 ohm tweeters.2 woofers per cabinet, 1 tweeter.
You need only one per cabinet. Set the jumper to 4-ohms. -- done.There are two undrelying issues though.1. MTM crossover frequency. It is my understanding that the crossover should be set based on your woofer spacing. For the speakers I'm working on, it's 2,250 hz. Just check that before moving forward.2. The book I'm using suggests a 3rd order crossover so I'm re-building mine with active 3rd order crossovers. a 2nd order (which these are) should also produce acceptable results just be aware that there might be some phase and dispersion pattern issues.

what type of speaker wire and gauge do I use to connect this crossover to the tweeter and woofer (please recommend products)
is there a difference in the type of speaker wire or gauge used on the inside of the speaker box to make connections than the wire used to go from amp to back of speaker box? Also are there special clips that can be purchased so that no soldering is needed on wire connected to the crossover?
Any speaker wire is really fine inside of a speaker cabinet. I personally use regular 16 gauge speaker wire and push on .205 terminals like the ones listed below.
