Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
The original damage calcs were off slightly (I made a typo in my calculations, using 453 attack instead of 463), but those are Jolly with Choice Band. Adamant would push some of those into 2HKO range with Stealth Rock. Of course, by switching to Adamant, you also risk being outrun and...
My gut reaction is that Aerodactyl is too strong for UU, but after doing the damage calculations, I'm not so sure. (All are max attack, Jolly, with Choice Band.)
Rock Slide vs. 304 HP/440 Def Cloyster: 57.2 - 67.4%
Rock Slide vs. 244 HP/572 Def Shuckle: 55.3 - 65.2%
Rock Slide vs. 362 HP/328...
I haven't used it in a long time, and I only had mixed success when using it before (probably due to me being a horrible battler at the time instead of merely bad), but I've always thought a Wring Out/Brine Omastar could work. Something like...

My only problem with this is that movesets are never banned: Pokemon are. If the moveset makes the Pokemon too powerful for a tier, the Pokemon is too powerful for the tier. (See: Manaphy)
I hate to quote myself, but I REALLY think Crobat needs some discussion and I have seen almost none involving it.
Whether you agree or disagree, it needs some talk.
Probably want to try that first. If you don't like that, you can go for another one. For example, I used to run
Blissey @ Leftovers
Bold / EVs: 148 HP / 252 Defense / 104 Sp. Atk / 4 Speed
Ability: Serene Grace
- Substitute
- Charge Beam
- Ice Beam
- Softboiled
and it worked great. Charge Beam...
Crobat should definitely be in BL. Base 130 speed means it outspeeds all but a handful of UU Pokemon without a +Speed nature. With one, it is outsped only by scarfers and Electrode. It has above average defenses (85/80/80) and good typing (three 4x resists and one immunity) to go along with...
Scyther is a great UU sweeper (too many Bug resists and too many Pokemon with >105 speed in OU) while Scizor has many options in OU (Baton Passing, walling, sweeping). I plan on using a Jolly CB Scyther with U-turn/Aerial Ace/Brick Break/Pursuit on my UU team and one day working the Swords...
I missed the Trick Room mention, but I'd expect most Skarm users to either Drill Peck/Brave Bird, Spikes/Stealth Rock or Roost in that order. I can't imagine one using Whirlwind unless Spikes/SR had already been fully setup.
Well, I can't consider anything with Life Orb bulky to begin with. With...
I would run Naughty instead of Brave and go with 112 HP / 252 Attack / 20 Defense / 124 Speed for the EVs. That minimizes Life Orb damage (349 HP means 34 taken away by Life Orb), still maximizes attack and lets you outspeed Skarmory so it doesn't Brave Bird/Drill Peck you before you finish it...
Scyther is my favorite U-turn user. 110 base Attack, 105 base Speed and STAB makes for a great combo. Although as long as Stealth Rock is on the field...
