Regarding your specific questions:
HA/SW: I've used HA over SW since it gives another cooldown for trash packs and is a nice DPS boost (i combine it with Pol's). I didn't really consider SW but (with no numbers to argue it), I feel that you want to ensure you are under cooldown for big pulls rather than having a more regular HP generation. The massive execute DPS from SW I don't know if it is needed (how many can you fit in on trash pulls - 1 maybe 2?). Make sure to not use focused wrath when you need to stun mobs (in particular demon part of auchouindon)
Trinkets, you don't need/can't afford stam if going for gold. Need your tank dps. Personally i'm running HA+Pols and Alch trinket as second one. If you have a scabbard use that in a slot for more DPS. Try to finish the previous trash pack with 3-5 HP so you can pull next with Sera immediately.
Stats: agreed that haste is not so good in CMs. Crit gives me the best performance - not sure between versa/mastery. I am busy replacing my haste pieces for raiding with something with crit on it.
