Couple of Macbook Pro Questions

[MRamirez181]

I recently got my first mac computer ( Retina Macbook Pro 2.6/16/256) and after playing around on the computer for a couple of days I have a few questions.
1. How do you delete apps from a mac? Tried and tried but can't figure this one out.
2. What issues should I look for on the computer before deciding to keep it? (EX: Image retention, dead pixels, ect.)
3. (I posted this one on a thread a few days ago but hasn't been answered) Do the iCarbons retina macbook skins leave the computer sticky after you take them off the computer when they have already been there for a long period of time? Need to know this one as I plan on selling it down the road and the skin could hurt the resale value IMO.

I can only answer on question:

Normally it is sufficient enough to put the application into the Trash, which can be done via going into the Applications folder (Finder > Go > Applications) and selecting the application or the application folder and dragging it to the Trash icon on the right side of the Dock.
But if you want to be more thorough:

Thank you, I would never have found that out. You would think there would be an easier way to get rid of an app completely.

Once you get the flow, it is easy, it only takes a minute or less. They are drag & drop application removers, but they are not as thorough. But normally it just suffices to drag the application into the Trash, no Registry in Mac OS X to **** things up. The PLIST and other setting files remaining are small and normally are not in the way of other things
