Congratulations ! Good Choice !
Mirage is a well-made CANADIAN boat. Produced in the eighties. Have a reputation for high-quality fibreglass and a decent turn of speed, although not in the J-Boat category.

Before you do anything with the rigging, get a Loos gauge. There are two sizes. You might be able to get away with the smaller one - it's about 10 bucks cheaper. Find out what size the rigging wire on your shrouds (the cables on the sides of the boat that go to the mast) are. If the clerk in the store tells you you don't need one unless you are racing - tell him I said he's an idiot. (just kidding - tell him you want one anyway)
Read the little booklet that comes with it and follow the instructions when you are re-rigging the boat.
Before you take anything apart - take pictures and label it. You don't need to undo the fastenings at the top of the mast. Just undo all of the fittings at the deck and then wrap your stays and shrouds around the mast.
Be sure to inspect to top of the mast to make sure everything is working (lights, antenna, etc. and make sure that nothing is siezed/broken/corroding before you put it back up.)
When you have the boat moved and re-rigged, come back and ask some more questions.
Good Luck - you're going to really enjoy your boat.
