IMO - The distribution phase is different than the accumulation phase... and therefore asset management issues are a little different.
Assuming you will need to spend the money during your retirement....
I would recommend that you read and study information that is focused on investment during distribution and techniques for producing income.
A couple of books:
- Ray Lucia has a book on his trademarked "buckets of money" approach.
- Paul Grangaard has a good book on the topic "The Grangaard Strategy: Invest Right During Retirement"
- Ed Slott has some good books on the use of Roth IRAs and taxes.
If you are a 4% er... then there are many whitepapers on that technique. The Financial Planning Journal has quite a few articles that describe that style.

Bob's Financial Website has some interesting research on the topic.

There are a number of legitimate and effective ways to create income from your assets. Take a little time to figure things out before you make any drastic moves.
Once you understand the issues and which asset management and income management approaches best meets your needs and tolerance for risk... you should consider developing a financial plan for retirement. The general consensus is that one should not take much risk with money that you know you will need to spend in the next several years.
If you are uncertain about the market (and I can see why you might be)... one way to ease into the market (whatever the allocation or investments) is to just average the money back into the bonds and stocks over time.
