Ballcock is leaking

I have a floating cup ballcock on my toilet. Recently, this part stopped working correctly & seems to leak air. Whenever it needs to fill up the tank, all it does is drizzle a very small stream of water(plus a sound of air leaking). Is there any way to fix this problem without replacing the entire ballcock? Can this be done without shutting off the water?

As a side note, this problem originated when I turned off the water at the toilet's shutoff valve. Unfortunately, the valve hadn't been turned for awhile and started leaking profusely. I got the leaking to virtually stop leaking(not completely), but ever since that incident, I've had the trouble with the ballcock. Do I need to replace the shutoff valve, or can I repair that too. I'm on kind of a tight budget, so I want to find the cheapest solution to both these problems. Ultimately, I just want my toilet to start working again. Any help with this matter would be greatly appreciated!

You're talking about less than $10 bucks to correct the whole problem with new stuff.
A new Fluidmaster float-cup toilet water inlet valve assembly costs about $7.
Get one. Follow the directions (yes, you will have to turn off the water at the cut-off valve).
Close the valve (use a pair of channel-lock pliers on the handle, if you have to).
If the valve is still leaking, try just tightening the valve stem cap (that the handle stem goes through).
If that doesn't work, just come back in here on this same thread, and we'll help you.
Good Luck!
