I have 26p props and need to buy new ones because these have been reworked multiple times, and I just want to start with fresh 26p props. The part number on my props are 48-931913 and 48-931914, but it seems like they may have changed the part numbers to 8M0151214 and 8M0151215. Are these still the same prop just a updated part number? Just want to make sure my current prop hubs and everything should work.

Yes, appears you've got the correct updated part numbers.
I haven't bought any props currently but I'd guess they wouldn't change the hub situation. Don't have any old hub part numbers compared to the ones suggested for the new numbered props if they did change.
Just buy the new props, get them and see and if your current hubs work. If not you'll have to order the correct hubs. Didn't specify if you have XR or regular Bravos.
I'm seeing $90.00 for the 1" shaft.
$150ish for the 1 1/4" XR shaft.
Although if it isn't a typo Great Lakes Skipper has a huge deal on the 1/1/4" XR hubs. HERE
