My opinion is that if you can avoid legal struggles it is always for the best. These things drag out and increase anomosity. BUT...is the amount of increase fair? Is it within the guidelines for your state? If the amount of increase requested is fair to you and her then call her up and say you want to agree on an amount. If it is not fair to you then call her up and say you want to compromise on an amount. If you feel you are not providing the amount you should be then swallow your pride and resentment and get this child support issue out of the way.
This C.S. stuff is just a festering wound. I've went the easy way and the hard way both and let me tell you the easy way is the best for avoiding all the anger and resentment. But you have to be fair to yourself. Don't agree to an exorbant amount that will leave you strapped just because you love your ex.
The rest of your attitude sounds great.
