You can ask the court to appoint you an attorney for limited purposes (child support and custody) but if there are issues of equitable distribution, maintenance, etc, you will need a private attorney. Contact your bar association to see if such an attorney is available. Your current attorney may also be willing to help you find a less expensive attorney.
The rates for child support do not change unless the legislator does so (which isn't happening any time soon).
The "self-support reserve" changes annually based on the federal government. You do not need to concern yourself with this sum unless the payor's income is below the self support reserve.
Additionally, the income "cap" changes every-other year and will not be modified until January 31, 2016.
Birth parents have a superior right to custody than all others. If there is some other person that you want to have custody of your child, make sure that that person (or people) are in the child's life in a VERY significant way starting right now. Document every aspect of their role in your child's life - keep journals, photographs, etc. Additionally, go to an attorney to draft an affidavit fully discussing your wishes. The affidavit may not be of any value but some judge may be interested...
The wife can file for divorce and proceed with or without the husband's appearance. The wife must ensure that the husband is properly served and that the process server completes an affidavit of service.
