Is there a task killer app on the phone? Did you uninstall any and all battery saving apps?
Which app puts that home button icon in the notification bar? What other apps are putting icons on the notification bar?

I think these two issues may be getting to the root of your problem.
For sure delete anything by facebook. You can get most of the same features from the mobile web version without it tying up so many of the phones resources. Also, delete anything that says it helps battery or cleans up background apps. These are terrible on the phones memory and battery. Any time you start closing down apps in the background for the sake of "Freeing up space" you are forcing your phone to do double work to open them back up.
I don't recognize the app that puts the icons in the notification bar, but they are most likely drawing resources.
Also, if you have gone through and disabled a bunch of the apps, you might want to go back and enable any of them that you are not absolutely sure you know what they do. Even if they are on one of the "Safe to Delete" lists, you may be using an app that needs one of these apps to run correctly. Also, many of the Google apps are tied together in the background, so disabling those can cause unintended hang-ups.
You can always do a full factory reset. Don't add or delete anything. See how it works for a few days. If it's hanging up and running slow with nothing added or taken away, I would think it's a hardware issue.
