I dont think there is any receiver out there that will let you switch 6 component video signals. A mid-fi receiver will let you switch 2 or 3 component inputs and 2 or 3 HDMI signals but I dont know of one that will switch 6 and 4 respectively.
If you must have 4 HDMI and 6 Component inputs, you will have to get dedicated switchers, look at DVI Gear website for some inexpensive ones. Further, if you are getting dedicated switchers, you might as well go the Pre-pro + 7 channel amp way rather than getting a receiver.
I noticed that you intend to get Axiom speakers. They are highly regarded on this forum. Make sure you also look at brands like AV123, Aperion, etc. for speakers and SVS, HSU, etc. for the sub. Demo if possible and dont skimp on them.
