I'm not sure it's reasonable to spend ~$3,000 on speakers and $200 on a receiver. That seems pretty out of balance to me. You will probably find that the new speakers reinvigorate your listening to such a degree that you become a bit more liberal with volume than you had before.
I agree that room correction is nice to have, and would encourage you to look at receivers in the $500 range that include preamp outputs in case you want to add external amplification later. Of course, you may not use either the extra power or the extra features, but you really can't know how the new speakers will change your habits or expectations.
