How Does Purchasing JB Apps in Cydia Work?

[HappyDude20]

I'm a total novice in this area so figured i'd ask.

W/ my JB iPad i'm realizing there are numerous apps I wouldn't want either a friend or girlfriend to see while they're messing around with it and i'm somewhere else.

I've never purchased an app in Cydia so can only imagine how that works. I'd guess they'd take a PayPal payment or something and it downloads to my iPad. But i'm also wondering if my iPad ever is completely restored, just how easy it is to get back that app that I purchased? Also, say I buy an in Cydia that I see fit for all my iDevices, is getting that app just a matter of visiting Cydia in each device and downloading it with no additional information required?

The app in question is either:

LockDown

mAdvLock

iProtect

Locktopus

Which allows me to password protect any apps I want; and with the new GF around, I could def. PW protect Photos and Videos and my FaceBook app.

As a side note: If anyone has an opinion about which of these apps is best, please do tell.

UDID, is this limited to only one of my iDevices?

Depending on the App (most) will allow you install on multiple devices.
