My name must be mud in the H-J household

On the contrary Chris, quite the opposite, Babs has always remarked how nice it is when friends on the forums help out in one way or another so there is no need for you to worry!!
As it so happens I always use LittleNavMap for flight planning, one of the best flight planners available, and it's free!! Though have not been on that site before and did not realise there was aircraft performance files well....You learn something new every so often!!
Can manage the default X Plane FMS reasonably but have always been a VOR to VOR pilot with the occassional ADF thrown in here and there!!
Going to have to sit through quite a number of tutorials it seems but as you wrote, it is going to be rewarding once I've cracked it.
Loving this aircraft and a real joy to fly though the pre-flights and engine start have caught me out and was surprised how long it takes to spool up!!
Righto back to the classroom go I.
Many thanks for the HU Chris.
Regards
Nigel.
