Shawn,

You do need to configure GP3 for external MCLR.  GP1 can be used as long 
as you don't actively pull it high.  I've always used this pin as an 
output and have never had a problem with debug or programming.  I've 
been using this type of header since it came out and have never had any 
problems.
