Is moldy sculpting clay still good to use?
If it's real clay, dug from the ground, it's fine to use with mould on it. In fact, mould improves the plasticity of clay (which makes it easier to work). The mould will all burn off in the firing. If it's synthetic clay, some sort of plastic stuff that hardens in the air and does not need firing in a kiln - sorry, no idea about whether mould affects it.
What are the stages a piece of clay goes through to make a finished piece of pottery?
1. Slip-watered down clay in a muddy form2. Plastic-workable stage; molding stage; can recycle; can join to other pieces3. Leather-hard-stiff and will hold its shape; join to other pieces; carve into; recycle4. Greenware-bone dry; can be carved into; very fragile; can recycle5. Bisqueware-fired once in kiln; can not be recycled; glazing stage6. Earthenware-second fire-low fire; can not be recycled7. Glazeware-second fire-high fire; can not be recycled; vitrified

Can you paint air dry clay before it is dry?
If you paint wet clay with any kind of paint, the paint will not absorb into the clay body. Acrylics would burn off in the firing. (you could paint them on after)Typically the first firing is the Bisque Fire. This is where the Greenware(dried clay not fired). Comonly fired at cone 06 the clay is sturdy and has a high viscosity (it can absorb glaze/paint). cone o4 is used for underglazes which are a different type of paint for ceramics.The second firing (Glaze Fire) is at cone 6. After the piece is glazed/painted it is fired and the surface is glassy. The piece is finishedIf you want clear/bright colors I would suggest using underglaze. You paint it on after the clay has dried and before it is fired. It only needs to be fired once.Bisque Fire: cone 06 approx.1,800 degrees F.Bisque Fire (for Underglazes) cone 04 1900FGlaze Fire: cone 6 approx. 2200F*Make sure that nothing is more than an inch thick. Less if possible. If there is a bubble in the body of your piece, when it's fired the air will expand and the piece will explode. (taking out everything on the kiln shelf with it.-this is the voice of experience.)
What is the process that a ceramist uses to remove pockets of air from wet clay?
if you are using recycled clay, wedge the clay on a solid surface, use your cutter, and cut in half, if you see any wavy lines in it, it needs more wedging. if you are using new clay you should not have to wedge but use it, making sure as when you are building that you do not leave air pockets in the piece work, otherwise it can explode in the kiln, worst case scenario

No, you sculpt the clay first and then bake it once you are through with your work of art.
Why is firing a ceramics piece of work necessary?
It is only necessary if you want to use the item and/or keep it in one piece for a long time; a dry ceramic piece will chip and crack easily and will return to its sticky clay state when wet. At least you can use the clay again !
