You can certainly recycle incorporation papers, etc. You can also bear the brunt of the legal problems that may arise if those documents are defective.

I think one really has to understand the legal implications of forming a corporation (what you can and cannot do, what you will and will not be liable for) before one can accurately assess the necessity of having a lawyer handle that task. Lawyers don't make money filing papers; they make money suing people who screwed up the paperwork.
