I read the Godwulf manuscript 3 years ago after reading numerous Spenser books and I am sure I enjoyed it more because I had read the others.
If you have an opportunity to get later books at a good price, I would do it. They will certainly not ruin your experience in reading the earlier books at a later time.
I find the Spenser series to be better read in order as you watch the characters develop and the writing get better.
