As Mike already said, don't use Cuervo Gold...it's a joven abocado and gold only by courtesy of caramel coloring, and by definition only 51% agave. Use the real thing, a 100% agave tequila. Probably your best choice is el Jimador Tequila, either blanco or reposado, depending on how full-bodied you want your 'rita to be. Tesoro is good. So is Camarena (softer styled though).
Cointreau is the best; that's why it's expensive. If you're looking for alternatives, there's Combier Triple Sec for a crisp, dry orange taste...but if you already have Cointreau, you're fine. You use small amounts anyway (too much masks the agave nature of the tequila.)
Fresh limes is the only way to go. If for some reason your limes are too tart, use just a touch of agave nectar, which is easy to find in grocery stores these days. Better than sugar, and has that agave taste to reinforce the nature of the drink.
Here's the important part: use lots of ice, mix it all in a shaker, and shake vigorously before pouring into a glass. It makes a big difference.
Salt rim on the glass is up to you.
If you're looking for authenticity, another drink that would fit, and you would more likely find in Mexico, is the La Paloma: tall glass, ice, silver tequila, lime juice, grapefruit juice, and fill the glass with Squirt Grapefruit Soda. That, more than the margarita, is really the standard drink in Mexico. (And if you want to make it a little exotic, top with a small bit of Luxardo Maraschino Cherry Liqueur...sort of a highball takeoff on a Hemingway Daiquiri with tequila instead.)
