Things you want in PvE:
Tanks: stamina, defence, resistances for certain bosses.
DPS: don't need as much stamina as shouldn't be hit(apart from aoe) if aggro is controlled properly. You want steady damage - so I guess +hit and such for rogues, rather than +crit - which can be a good way to gain aggro and hence die. Rogues are squishy. Don't do silly things like super duper crit ambushes before tank has aggro.
You want your casters to have enough mana to last the fight and +damage and +hit to make an impact - plus crit is a good way to get your party wiped - a few crit frostbolts can steal aggro off a tank.
Your priests will want to have good spirit so they can regen mana throughout the fight and plus healing so their heals are strong enough to keep tanks alive.
Warlocks are a funny class for pve - they need lots of Int in PVP coz they don't have time to stand there draining health for mana - but in PVE they need more stamina as it gives them more mana in the end and can easily be replenished by healers.
There's nothing wrong with crit chance in PvE, unbuffed I have just over 34% crit chance, +5% hit chance (another +5% from talents), and 4500hp, although only about 750 attack power. If you know how to control your aggro then you won't keep button mashing after 5 crits in a row and 0 feints against a boss with aggro reduces on the MT. In Molten Core and ZG stamina isn't really an issue for rogues, just stay above 3k unbuffed and you're fine, but it'll help a lot in the second half of BWL and AQ (my record HP is 7200, <3 flasks

).
If you're guild is wearing mainly PvP gear then the biggest problem will probably be healers mana, a few Dire Maul runs can gather some really nice mana regen gear though, also some very nice loot in ZG to get ready for the longer fights in MC.
Only problem i find is trying to explain to the other two rogues that the reason i wipe the floor with their DPS is SLICE AND DICE! omg -.- why dont ALL rogues use this? i use it as my second finisher in any fight... normally if fighting elites like in ZG it would be a 3 or 4 point evis and one or two point slice and dice next and normally compared to the 2 rogues who dont use it i come around around 7 - 10% more then them in overall damage (not sure about the % higher on DPS never checked)
Slice and dice can be better than eviscerate, but it depends on your gear/spec. S&D will scale to become better as your gear does, and eviscerate will stay the same damage no matter what. A while ago when I was using Perditions Blade/Heartseeker and without Dual Wield spec, I worked out that eviscerate would make more damage than S&D. Now I am using Perditions Blade/Sand Polished Hammer with Dual Wield spec (combat daggers ftw (17/24/10) - great for raiding, crap for everything else) and S&D will give me more damage damage than eviscerate.
IMO Combat spec rogues are much much better for PvE as you said you need to maintain DPS which a combat rogue can do without a doubt and is one of the reasons we have done quite well for our 3rd run (IMO anyways)
The 'burst damage' associated with daggers is only talking about very small preriod of time (1-2seconds), once you're out of energy there is no longer any burst damage. Constant DPS is had by both swords and daggers in PvE, swords with 1 SS every 2 seconds, daggers with 1 BS every 3 seconds. In fact dagger rogues are usually at the top of the damage meters for us, apart from the brief time where Thunderfury was still good, then they nerfed it and he's back below us again. Although we've had ****ty luck on sword/fist weapon drops, a hand full of Brutality blades, 1 Vis'kag, and that's it. No Claw of the Black Drake or Chromatically Tempered Sword or that new one that drops from Fankriss in AQ40.
