I have just carried out the upgrade and found the centre reading light a pain, maybe because I attempted it in the dark 1st time round and with a little guidance from Trups managed to figure it out and 2nd time round literally a few minutes and it was done.
I took some pics and thought would share a little how to if cool. See below..

The rears were exceptionally easy, and just a case of popping the cover off and replacing the bulbs for LED's. Again the vanity lights were easier too, when you pull the visor down as you are looking at it there is a small spring clip on the left hand side of unit. Pop a wee thin flat had in there and the lens will just pop off and then replace bulbs.
I am still to do the glove box but will leave it for time being and do it on weekend when I get my next spare minute...
Sorry that this has been covered in the posts above but I thought it may help having some pictures.
