Answer 1

You can cache your images using a pool of SoftReferences (http://developer.android.com/intl/de/reference/java/lang/ref/SoftReference.html). This will allow the OS to clean them up if it's running out of memory while still allowing you to access them. This should help with #2 and #4, but I am not sure what you mean by #3.
