Hi, and welcome to the forum!
I think that the Pioneer is a good choice. My last two receivers are Pioneers, and I've been really happy with them. I don't have any opinions on the brands or models of speakers that you picked, but others here might.
The thing that stood out to me was that you have different brands (with different drivers) for your front left/right speakers versus your center channel. Ideally, you would use speakers that are tonally matched so that the sound is consistent as it moves across the front (say, for a motorcycle going from left to right in a movie). That said, the MCACC auto calibration system in your Pioneer may be able to make them sound nearly the same. Your VSX-1326 has what I think is Pioneer's most advanced MCACC. It made a world of difference with my speakers in my room (although, they were the same brand and series).
So, my suggestion is to get your system set up, run the MCACC calibration on your Pioneer, and then determine if you think that your front and center speakers are a good combination.
