You would want an adapter like this:

I am not sure what SIM card size the Franklin R850 uses, so it might be that you will need an SIM card adapter for it to fit.
The MC7455 is not sold on Amazon. You would need to go to eBay:

As for antennas, one of these should work nicely:

Sprint's signals are 90 degrees out of phase like that dish should do, so it should work well. You would also want some way to mount it, such as this:

You would also need some cables to attach it to the radio. These could work:

The best ones are LMR600, followed by LMR400 and then LMR200. They are not a common cable type, so you would likely need to order from somewhere other than Amazon. Whatever you do, make sure to order a 50 ohm cable.
That is $349.98 before the cables and the $260 for the first year of 4GCommunity + their equipment. The first year would be at least $632 in total (although I do not know what the shipping costs are on those cables). After that, it is $168 a year.
You would need to work out where the Sprint towers are. I suppose you could do this by turning the antenna on the J mount while monitoring signal strength from the Linux command line.
You likely will also want to confirm that Sprint uses band 41 in your area before doing this, but I am under the impression that basically all of their towers have it. It is just too weak for most people to get, so they connect on lower frequency bands that have less bandwidth and are shared by more people. Directional antennas can fix that. You could ask about what bands are available in your area in /r/Sprint.
Anyway, that is all I know. I do not plan to do this myself for at least another several months.
Edit: You can use the OpenSignal app to figure out where the nearest Sprint tower is.
