Tree, with a high end receiver, you really get the best of it. You will have (generally) more flexibility and features than a separates pre/pro (unless you spend lotsa$$), you will have more than enough power and the receiver can act as a pre/pro for a big honkin' amp later if you need it. Looking at the info that has been posted - you know everything you need to know. Spend the bucks my friend, there is no mistake to be made with the menu in front of you .
