I have a friend that participated in the games. She entered 4 cycling events and a triathlon event. She did the same events two years ago and won gold in all five events. This year she'll be 85 and she hopes to repeat her last performance. Is there a web site that you know of that lists the results of the races as I haven't seen her since she left (she'll be going to Canada for a few months)?

As for a cyclometer with all that you are asking for, the Cateye mentioned by Tpcorr is a good one. I have the Cateye Strada Double Wireless which has cadence built in but does not have a function for adding a heart rate monitor. Personally, I prefer a separate HRM because I like to know what zone I'm in and what my heart rate is when I'm sprinting. It's a bit more difficult to do that with a do-everything cyclometer when you have to constantly use the mode function to flip through the various views to get from one view to the other. My HRM is a watch type made by Sigma. The other advantage with having a separate HRM is that it can be used with other sports events.
