Not sure about the image stuff.. from what I've seen you generally would load/cache images at the start so that you don't hit any delay when you actually need them. Depending on the size of the images and number of them, you may run up against the 16 to 24MB ram limit per app. This has been discussed in other threads regarding some of the limitations of Android presently with regards to iPhone quality games and music apps.
As for the classes, unless the Dalvik JVM is completely different, classes get loaded when needed.. or instantiated/accessed. They will reside in the .apk file, but only should consume memory when they are first needed. It's been a while tho since I got into how the JVM loads classes. The one aspect I forget how it works is if a class imports another class... let's say you have Class A that uses Class B in a method.. there is an import (unless they are in same package) for that class B. I forget if the JVM actually loads the bytecode for Class B at the time Class A is loaded due to the import... or if it wont bother looking for Class B until it's referenced in the one method that Class A uses it in. I think it's the latter.. I think the import causes the JVM to find the class..but not actually load the bytecode until needed.
