Keegs,
Keep in mind that there are different types of annuities (e.g., fixed versus variable) with their own advantages/disadvantages. Humberto Cruz is a financial columnist that I find informative. He has written several articles on annuities. Here's a link to one such article.
Humberto Cruz: Annuities can be valuable slice of retirement funding pie | Dollars & Sense
Both Wellesley and Wellington are great funds, in my opinion. (Disclaimer -- I am a Vanguard customer). Both have relatively low fees for actively-managed funds. The Wellesley fund maintains an approximate 40% stock/60% bond allocation, while the Wellington fund maintains an approximate 60% stock/40% bond allocation.
Vanguard's Target Retirement funds are index funds with stock/bond allocations that change over time; e.g., the Target Retirement 2025 fund will gradually decrease its allocation to stocks and increase its allocation to bonds over time.
The beauty of the hybrid funds (Wellesley, Wellington, Target Retirement, Life Style) from Vanguard and other relatively low-cost companies (e.g., Fidelity, T. Rowe Price) is that you don't have to worry about rebalancing your portfolio -- they do the work for you. Set it and forget it.
