Do you have a copy of Protel's CircuitMaker.  Much easy to draw simple
schematics, plus it is a pretty neat Spice simulator too...

This does work but maybe I've explained it wrong ... I'll try to draw
the schematic in paint.

IMHO that can't work: the diode from MCLR to Vcc will prevent MCLR from
rising above Vcc + 0.6V, which is not enough to enter programming mode.
