I shot a number of Weddings in the past decade (usually 2 per year, not how I make a living, but I apprenticed so...). I wouldn't worry about getting "Raw" files. While I always shot Raw I always delivered jpgs, I think at 8 megapixel equivalent (My Canon 5d is only 13 megapixels.). This will be Fine for most size prints. 2.5 megapixel is clearly is web only. I processed the images in lightroom to give them the look I wanted and delivered a large set of high quality jpegs. The post processing / sorting of files takes a lot of time, so not having to do that would lower the price. Digital wedding photographers take a lot of photographs so sorting them can be onerous. Play that the fact that you'll sort and post process yourself. Plus some photographers don't want to give you all the photos as invariably some are Out of Focus or not great. Your on the right path negotiating before hand. Expect to pay extra for the rights and images. If you find a photographer that will give those to you, expect the cost to be baked into the price. Its Still better than having to go back to the photographer for every print.
