Ooh I'm NW15 too!
Glissade is pretty, though i find that it is a little too glittery (Not in the Naked You way though), so I prefer that one for night time over a blush
Lightscapade for SURE for your highlight- Shimpagne is pretty too.. but can easily make (me at least) look oily, as it's very very... shimmery. Lightscapade = LOVE
As for blush... I actually really like Petticoat and Stereo Rose. Yes they need a super light hand and you'll need the 187 to help you, but it's worth it!!
I have porcelain pink, but not so keen on it.
As for bronzer/slight contour, So Ceylon is the one
I use MSF Natural in Light for my foundation
As you can tell... I love my MSFs
