I believe you should pull a vacuum on the system with a vacuumpump and guages. Let it sit to see if it holds, then recharge the system with the proper amount. Some one correct me if wrong.

gfreek is right. The system would need to be put into a vacuum and left there to see if the system holds the vaccum. If it does then it can be recharged.

So if i pull the suction hose out,do i need to discharge the system first?if so how do i go about doing that?Also,the A/C system was perfectly fine until i found a leak on the suction hose.So do i still need to do the vacuum check?

If there is any refrigerant in the system it does need to be pulled out. It boils at a very low temp and if suddenly released it will cause you a good deal of personal damage. The vac check is to make sure that there are no leaks in the system so that you are not wasting your money filling a systemthat will leak.

Also putting it into a vac removes all of the air in the system which does nothing but interfer with the proper operation of the refrigerant. It also removes the moisture from the system which will eventually do internal damage.

I would recc that if you are not real knowledgeble about AC systems, the danger of then and how to work on them that you take the car to a shop. Better to pay someone than to get hurt.
