Ginger is wonderful for kicking colds. Brew some tea with slices of fresh ginger, and sweeten it to taste with honey and lemon. Or Cold FX. It's the active ingredient in ginger, just in a measureable doseage. The regular formula works, but three days on the Extra Strength with kill the cold dead. That's what I did with my last cold.
Also, sounds like your throat needs a little TLC, too. Zinc and echanaecia (spelling, anyone?) drops work wonders. Though the only ones I've found near me tasted terrible and were gritty...but they did the job, so I took 'em. And stay away from caffeine, nicotine, alcohol, and salt. They are all diuretics and will dry out your throat (and everything else, too.) Stay away from hot and cold drinks, too. Stick with warm. And if your throat's really bugging you, when you feel the need to cough, take little sips of air until the urge passes. Sometimes this works, other times it doesn't, for me anyway. Depends on the type of cough, I guess.
I hope you feel better soon!
