Answer 2

Hmm. Your question falls into two basic sub-questions:
1) How do I deal with touch events? and
2) How do I move stuff around the place?

I think you're going to need to start with some basic examples of both and then wire them up together. Until you understand both aspects you're unlikely to get very far.

Here's a good tutorial which combines elements of both: http://eleanordarephdjournal.blogspot.co.uk/2011/03/example-of-simple-animation-and-touch.html , once you can understand what is going on in here, you'll know what to search for to find out more!

Happy hunting!
