Your receiver should be fine. It would take some seriously inefficient speakers to cause trouble. Just stay with something 8ohms and 90+db sensitivity. The HSU's are awesome bookshelfs, I had a pair a little over a year ago and demo'd them a few days and they are very nice sounding, although I ended up keeping the Arx speakers and sending several others back. HSU probably would have been my next choice if they had matching towers, but thats the only bad thing I can say.
The HSU subwoofers are also great and you should be able to get the HSU speakers plus the subwoofer as a matching Hometheater package.
