Which bike to get?
Some of the McGyver stuff is a need to have unless you want to be pushing the bicycle. I don't consider it an official ride until I get a flat. I have the worst luck on bike rides especially right after the rainy season stops. All the crud on the road from accidents etc tends to get washed right into the bike lane. Glass, pieces of metal, etc. Yesterday it was a piece of copper wire that went right through the tire.
Congrats on the bike and I hope you enjoy it. Cycling is my favorite exercise. I get a better workout running, but I much prefer cycling.
