Have you given consideration to upgrading to iOS 5.1.1. Granted, I have and iPad3, but I had (have) no problems with Action Menu Plus Pack, Gridlock, Folder Enhancer and Springtomize 2.
I realize that anecdotes aren't data, but maybe your iPad2 will work better on iOS 5.1.1. I've heard it's more stable than iOS 5.0.1. Just a thought...

What anecdotes aren't data? I don't understand that. Maybe my iPad will work better on iOS 5.1.1 but I can't download it atm because I'm overseas on a deployment and have limited ability to upgrade. I hope it's more stable. I'll have to wait and see. Download speeds here are like dial-up. Yeah Action Menu (does work great), but with Action Menu Plus, it lags and glitches with the options given. Off topic: Can't wait for iOS 6 though! I also noticed that with low ram, the tweaks does not perform well and start acting up.
