I'll offer an opinion here.  It would seem that while taking the heater 
core out of the loop will lessen the total amount of coolant in the 
system, it doesn't seem like it would make that much difference in the 
scheme of things if everything else is in good condition.  Especially 
since w're not seeing summer time like temps yet.  Not sure what part of 
the globe you call home.  But around here it has only reached @ 80 
degrees so far.  
Back in the day (forgive the old timer moment here)I had a '61 Plymouth 
in which was installed a shut off valve to the heater core.  In the 
summer time I would close this valve to keep the hot coolant from 
flowing through the core.  The idea being it would help to keep the 
interior temps down in a non-a/c car.  It never affected the engine 
operating temps.  
I think all of the suggestions given here are good ones.  Basically they 
all lead to making sure all of the components are operating at peak 
efficiency.
With all this in mind I have my own over heating issue as noted in an 
earleir post.  So I should probably follow some of the advice offered 
here as well.  The first thing should probably be to have the radiator 
flow tested.
