It sounds to me like you have already answered your own question. There just aren't any hard and fast rules with kids. It's really best that you work with him where he's ready.
Does he like to draw? It may look just like scribbling now, but it's important to give him chances to strengthen his fine motor skills. You can introduce tracing a little bit now but he may not be able to follow so I'd start with big circles and squiggly lines.
It's wonderful that he likes to read to you. How does he do with listening by himself? You could get him some books on tape and see what happens when you walk away. The older he gets the more you are going to want to see him spend some time working on his stuff while you get a few things done.
Are you painting with him? I have a group of children that range between 2 and almost 3. I just ordered tons of painting supplies and have long sleeve smocks coming for them. It's been quite some time since we've done anything other than water colors. So last night I looked around the net and found so many sponge shapes, paint rollers with textures and all sorts of fun things for the younger kids to do with paint.
I look forward to the rest of the answers. People have such great ideas around here.
