If you are referring to the bike's frame I believe you meant to say 56 cm, which may be the best size for your 5' 6" height. But how well it fits depends partially on how the particular bike manufacturer measured your bike, because that varies widely between companies. It will be best if you find a good reliable LBS to help with your fit.
As for your foot hitting the wheel, if you mean the front wheel that is known as "toe overlap". And this problem is very common and should not be of much concern. It is not possible for your toe to hit the front wheel except when riding very slowly and turning very sharply, as in a parking lot. On the road it can't happen unless you come to a sudden stop.
Your bike fit should be based on a number of variables, especially the overall size of your body, your torso vs. leg length proportions, and how upright you need to be.
Even if you have 3 fittings by 3 professionals you may get 3 widely different opinions. Still you need to have at least one expert check your fit.
edit: Good advice from others above.
