The toy library would be a great idea, I don't think there is anything like that here.
I should definitely bring DD some cardboard boxes from work occasionally, she would love to have tools too. I was thinking of getting her some kind of toolbox, she has been fixing her dolls stroller for a while.
I actually packed most of the toys away and then every now and then give her a box to go trough. She likes to look at them if they have been gone a while but does not really play with them.
We have magna-doodle too, DD has been using it since 9-10mo. Ours is small so we can take it to restaurants too.
I used to play with Playmobiles as a kid, too bad they are all at my parents house on a different continent.
