It would surprice me *very much* if the connector isn't documented in the PICkit2 documentation ! I just checked and of course it is, on page 9 in the "PICkit? 2 Programmer/Debugger User?s Guide". You havn't even cared to look in the user guide, have you ??

(i.e. = > is it OK to have it floating when the Pickit2 isn't connected)? Again, you havn't even cared to open the datasheet. Section 14.2.2 on page 209 clearly answers this. MCLR shoud *not* be left open. And you should *not* try to use "internal MCLR" at this stage. There is no reason to go into details at this stage, just don't try it...
