Ziopfan, investing wisely is important but so is spending. Whatever portfolio you decide on, after projecting income as best you can, take care that your spending is within the expected income... maybe with some safety margin.
Is the retirement inflation adjusted? If not, bear in mind that inflation will reduce its value over time.
Opinions on the best asset allocation vary, and many have good reasoning behind them. One tool for observing the past result of many different asset allocations is portfoliocharts.com. The site also has explanations of most of the main investment types, and a set of calculators for projecting returns in various ways.
As someone linked above, the Bogleheads community has many knowledgeable participants with detailed useful advice on the details and mechanics of investing. That is their main focus, whereas this blog has investment discussion as a mere adjunct to our focus on achieving life goals cost efficiently so as to be safe and happy within the expected income.
The 4% rule is one quick and dirty approximation to get in the right ballpark. A 50-50 stock/bond allocation is perceived as likely to provide safe withdrawals of 4% minus fees, without running out of money for at least 30 years. Historically, it has had at least a 95% chance to succeed as described. So after making an allowance for inflation (complex, but say 30% off as a beginning estimate) to your fixed retirement, take 4% of stock/bond investments to get your income. If your expenses are less than this, you are probably in a safer ballpark once you get your fees down to a dull roar. If your expenses are more, keep learning and calculate more precisely so that you can make wise decisions about your lifestyle as well as your investments.
Vanguard's advantage is to reduce those fees on the equity (stock) and bond fund investments. It has a big cost advantage for you compared to most companies.
PS. Quick and dirty analysis: If you sell the 500k property with a 30k sales expense, you end up with 1.77M for financial investments. By 4% rule, roughly enough to provide $70,800. Using 30% inflation discount on pension, $54,300 x .7 = about $38,500. So very roughly, $109,300 pretax. You should calculate your tax situation carefully too.

It sounds like you are somewhere near the area where you can cover your actual spending, but whether you're above or below will depend on the specifics, so your task is to learn them. Keep sharing the details to refine the analysis.
If you conclude that some adjusting of costs will be helpful, you can post a case study of the spending side in the Case Study section.
