Shipping based on some rules?

[ggouweloos]

Wonder is this is possible.

Q1: I have some fragile products, can I mark them in the shaop as being fragile?
Q2: I want to have different shipping for fragile products (insurance). This is not an option for the buyer, it's just a fact from the shop holder. fragile = insurance.
If 1 fragile product is there I need the insurance shipping.
Q3: Also I would like the insured shipping with a total order amount above 30 Dollars.

Any ideas on this one?
