My 3yo is similar. Regarding the packing away of one toy before another is pulled out... I aspire to that and sometimes enforce it, especially with jig saws... but not always. I also find that he obeys others better... so I don't think it laziness... more just disinterest. He usually responds to bribery. If I say that I'll read a book he will do it quick smart.

I still have to wipe him at the potty. I'm ok with that. He goes to the potty independently for a wee and will pull his pants up by himself... it's just the wiping I prefer to help him with. He turned 3 in June... and I guess i won't expect him to be totally independent until closer to his 4th birthday.

These milestones can be reached quite suddenly... who knows, maybe next month will be a different story?

Also with the packing away thing... it's good to be able to get other people to ask them as well. If I have a friend over for coffee I might ask them to ask my son to pack up before he comes and has a biscuit while I prepare coffee... know what I mean? Less drama and the more your rules are repeated by others the more it sticks with them. I find that when someone else asks him he 99% does it straight away. If I ask him he will avoid it unless i bribe.
