Could you be a little more specific...? If with "main" you mean a "mainsail", then it's kind of a strange question as the Laser has no other sails. Or are you talking about a Laser 2 or some other multi-sail "Laser"?
With the rigging (meaning "control systems") you can choose any level of fanciness and do fine. What's the level you're aiming at - local, national, recreational only?
You do need well-working control systems (it's called an "outhaul" by the way), but of course they don't have to consist of the latest or most expensive parts. You said you're "hoping" to sail a Laser, does that mean you already have a certain used boat (or several) in mind? You should first decide what level of racing (or non-racing) you want to do within a couple of years, and then look for a boat in the corresponding price range. When you have something to show (yes, we always want to see pictures!), then we can recommend possible upgrades.
Is there someone at your club who knows about these things that you could talk to?
