Micheal, if you do a search for "starters" here on the forum or on the internet you will get a good idea of what a starter is and how to use one for bread or pizza making. I don't know your experience or background but if you are just starting out, I would recommend just sticking to commercial yeast until you are fairly comfortable with the whole process of dough making and the results. It's just not necessary to add more variables or complications at when starting out. Not that starters are that complicated but it's another headache you may not wish to deal with right now.
As far as bread making, you can also search youtube for lots of videos on "preshaping" and "shaping" of the dough. There are many ways to make bread dough but generally the dough is left to bulk rise. After this initial phase, the dough is taken out of the container, dusted with a little bit of flour, and several folds are done to get the dough into a ball shape (this is preshaping). It is allowed to rest another 30-40m, where it is then dusted, flipped over and now shaped by doing a series of folds like folding a sqaure envelop. Top to bottom, left to right, right to left, and bottom to top or in an inorder. The dough is now left to proof up in a proofing basket.
After the dough has done it's final proofing, it should be handled as gently as possible to not degass it. It should be minimally molested at this point. It can proof seam side down or seam side up. It is then loaded onto a hot stone or into a hot clay or cast iron cooker and covered. Make sure the cover is tall enough for the bread to rise and expand.
I, along with countless others here would highly recommend buying Chad Robertson's Tartine Bread book. It is WELL worth the money and can teach you a lot about starters, and how to make great bread. It really teaches you the foundation necessary for bread making and ultimately dough making. If you search the forum for "tartine" there are several threads started that reviews the book and the breads you can make from it. Many of our members including myself have had very positive results after just one or 2 tries.
