I think your post makes perfect sense.
Your room size is going to play a big factor in how much power you will need. If you have a very big room then I would go with the amp that puts out the most power. I would assume you have a decent sized room or you wouldn't be looking at such big speakers.
It's pretty hard to beat the bang for the buck factor of an integrated. My opinion is that you can get an integrated that sounds as good or better than a preamp at the same price and you still have to buy an amp and a set of cables and a power cord and another shelf space etc...
