From what I have read afterlife was part of the < at least Welch, beliefs. Meaning of life and good/evil seem to be common for most organized religions.
Not to be difficult in your personal direction, but to be difficult in a general direction;
Unless a person is of the mentality to ask god what is right and wrong, which many people of non-mainstream faiths are not, then religion doesn't have to answer the questions that life experience and society already have sewn up.
In a faith, I don't need to say that lying, cheating and stealing are not ethical practices, because should you lie cheat and steal, you will experience real life consequences that will hopefully teach you the lessons that you haven't learned yet, and will inhibit you from pursuing meaningful spirituality in a way that is honest with yourself. Life is the school. You will learn what you need in a way that you will remember it, or you will experience the lesson again, with increasing return. Hopefully this time you will remember.
Most religions spend a lot of time looking at how mankind should treat each other, and very little time talking about how mankind should look at god.
The other 'what should I do with my life' question is one that is answered through practice not by practice. If a dogma attempts to set a meaning of life, no matter how obscure or rhetorical, it becomes dated. Suddenly there is a limit to how long the path will remain workable, because there is no meaning in life that isn't subjective to an individual, and the time in which they live. Even the lie cheat and steal ethics have limitations and perspective by which they are given degrees. Ten years, or a few hundred miles can make incredible changes to how much of the aforementioned is acceptable.
Short of live long and prosper, but both prosper and long being subjective again seems sort of trite, summing up the purpose of the universe in one to two easy chapters/ sentences?
