I am replacing my bathroom sink faucet. The supply line is 1/2" and the instructions for the new faucet states that a 1/4" supply line is needed. The current supply line is a grey solid tube and seems to be in good condition. Can I use the same supply line for the new faucet? If so, how do I make this work?

There should have been a 'packing' in the stem assembly. This is usually a gasket or a series of gaskets that prevent water from seeping around the stem when the stem is in the off position. If the packing was in good shape (no cracks or brittleness) and was seated properly then I would say it's time to replace the whole fixture.
In my past experience if the leak doesn't come from the stem or the packing around it, then the time finding the problem and the cost to fix it usually is not worth it for a cheaper fixture.
Faucets are usually 3/8, so you would need a 3/8 brass nipple
If not, they sell many different size brass nipples.

I've used channel-locks and crescent wrenches, but a basin wrench will save you some busted knuckles. I think that your 1/2" supply is probably coming out of the wall and is grey Polybutylene pipe? If so, you need a 1/2" PB x 1/4" PB shutoff valve, or an adapter to convert to PEX and then the angle shutoff valve.
If you do indeed have a 1/2" supply to your old faucet (very odd indeed -- are you sure that it isn't just the connecting nut that is 1/2"?), then you can probably replace those with braided supplies of the proper size on each end fairly easily. If you post pics of what is going on we can give you more specific advice.
