I am glad you are looking ahead and are trying to plan how you will move forward. You and your husband can agree to anything and you will need your own attorney to make sure that the agreement is enforceable.
As for spousal support: If there is no previous agreement for contractual alimony, then the judge is governed by the guideline of the Texas Family Code. you may be eligible for maintenance under T.F.C. Chapter 8 which prescribes an amount no greater than the lesser of $5,000 or 20% of your husband's GROSS (not net after taxes and insurance).
As for child support: If there is no previous agreement for a specific amount, then the judge is governed by the child support guidelines found at T.F.C. Chapter 154.
I hope this response has been helpful.

Child support and spousal support are separate. Child support is based on a percentage of the noncustodial parents income. It is not based on your needs or lifestyle.
Spousal support is a possibility but there are too many factors to go into here.
You should talk to an attorney to get more information about what you can expect.

First, I am sorry you are going through a divorce after such a long marriage. You are smart to begin thinking ahead.
Child support is typically awarded based upon a formula using the income of the person paying the support. There are other possible factors a judge may consider, but typically the support calculation is based upon income.
Spousal maintenance is something you and the other party can agree to, or a judge may order, with the amount and length of time depending upon the circumstances. There are criteria you must meet in order to be awarded spousal maintenance.
If you have not already done so, you should consult an attorney. An attorney can help you view your options realistically and will be able to assist you in negotiating the best possible settlement.
An attorney can also assist you in keeping the process civil and in keeping the ultimate costs down.
