My advice is to forget about mozzerella for a while. it is the only cheese that has beaten me and it's done it twice. The quick mozzerella came out ok, but it doesn't melt like it should.
It is actually one of the harder cheeses to make. Feta is easy, caciotta is easy, hell I even think of camembert as fairly easy, but mozz is just a pia. There are many cheeses out there and many are real simple to make and some like feta are almost foolproof, so don't aggrevate yourself with it.
