Welcome to the casting world, you'll find it rewarding and a hobby onto itself. Since you reload you obviously enjoy tedious, repitious things that require patience and attention to detail, not many people do so that is a major plus.
WW are a good start and for basic bullets will work very well. The thing about casting is that you can custom make alloys for different uses, such as using pure lead and tin in a 16:1 ratio for older guns like the .45-70 or bump your alloys up to near linotype hardness for shooting thru high power rifles.
One of the most rewarding aspects of casting is to find an alloy/load that will shoot to near the same point of impact at around 50 to 100 yards that your hunting rifle will shoot to using jacketed bullets. It is great practice for a fraction of the cost and the feeling of satisfaction is just amazing.
Lyman's Cast Bullet Handbook is always a good start but thanks to the internet and some links already given there is a wealth of information available to you that us old timers didn't have.
One major word of advice I can give is: Safety.
You will be working with molten metal, and it is unforgiving in the damage it can do to you or anyone you have helping. Be sure to wear long pants, leather boots, a long sleeve shirt, gloves and above all else eye protection.
I can't stress the last item enough. One drop of molten lead in your eye will cause a lifetime of misery. Years ago I had my Son helping me alloy some WW's and other ingredients, it was August and very hot. I was in the process of pouring lead into ingots and explaining to my boy about how dangerous it was to get water into the mix when a single drop of sweat dripped off my nose and into the pot. The resulting explosion lifted molten lead all down my front. Luckily I was wearing a denim shirt and gloves as well as goggles. After all was said and done I had burns on my lower face/chin area and when I took my goggles off there was a nickle size glob of lead splatter square in the middle of the lens of my right eye. Had I not been wearing those goggles I would have definately been blinded in that eye.
Enjoy the hobby but use caution. You'll find that when people find out you cast your looked at like some kind of black magician, most folk don't understand it, but it is very satisfying to make your own bullets and make them well.
