Two suggestions: spend one summer sailing BC coast, perhaps getting all the way to SE AK. or out to the Queen Charlotte Is. The next summer circumnavigate Vancouver Island. After that, you will probably be ready.
My advice would be not jump to sail down the west coast as soon as the boat is ready. Its a long way to decent cruising grounds and it's a difficult trip back up the coast if you decide you really don't like it. Besides, BC and SE AK have some of the best cruising in the world. You're lucky to live where you do.
Don't be in too big a hurry to leave.
