Going back to your specific question,
Gatwick - security at Gatwick is excellent, so much better than Heathrow, even at the peak of the holiday season. I'd not bother with Fasttrack, which has a limited number of channels. Head to the main security gates, use the ones to the right (they're at right angles to the larger line of them), and head to the scanners towards the right. I rarely have to queue at all.
Dubai - show your boarding pass or fast track card and they'll let you through. Some Gatwick flights land outside peak hours and you'll not have to queue for long.
I've never removed my laptop etc at Dubai and they just don't seem to care (although I was once pulled aside for having some magnetic whiteboard tape in my bag, so someone was awake that day)
