You want the same uF number.
You want the same or slightly higher voltage rating as printed on the cap to be replaced.
If it says 10V, get a 10 or a 16.
If it says 16V, get a 16 or a 25.
You want a replacement rated for 105 degrees centigrade, not 85 degrees.
You want one that specifically advertises itself as low ESR (Equivalent Series Resistance)
It's not going to have a specific frequency rating on it.
You aren't going to find that kind of capacitor at Radio Shack, and you probably won't find anyone working there who knows what you're talking about, assuming you find someone there who even has a clue what a capacitor looks like.
You could try any nearby electronics repair shops and ask if they have low ESR caps in stock for switch-mode power supplies.
If they do, show them the supply and the cap and ask how much to have them unsolder the old one and solder in a new one.
If they want $5 for just the cap itself, they're making a pretty good markup on it, but you'll have it right then and you can go back to Radio Shack for soldering supplies.*
If they'll do the repair for $35 total, try to get a package deal on both repairs for no more than an extra $10.
You're paying them for their time and for knowing what to do as well as the price of the part, and that's time they can't spend on a repair on which they'll make a lot of money, so don't just assume they're out to cheat you.
*If you wind up doing the soldering yourself, come back here and ask before buying any soldering stuff.
