Pennsylvania has a child support program which can help you get court ordered child support from the father. You don't necessarily need a lawyer to get a child support award. For more information and to get started, the child support website is here:
Custody is a trickier topic. In order to get sole custody, you have to convince the court that it is in the best interest of the child for you to have sole custody. There is a presumption that shared legal custody is best. Shared legal custody does not mean that your son won't live with you permanently, it just means that you and the father would share decisions regarding your son's education, medical treatment, religion, and so forth. Some parents will bring a custody petition, and if it looks like the court is not going to give them what they are asking for, they will then hire an attorney to protect their interests. This may be a good option for you.
If you can agree that visitation will take place at your home on your terms, then you don't have to have a court order. But if you can't agree, you should get it in writing and ordered by the court. Usually it is the non-custodial parent who petitions for visitation rights. At that point, you would want to make sure to have as part of your order that the visitations will be in your home.
