Adding more gesso to your canvas is absolutely fine if that's your preference. And if your canvas is pre-primed, you can easily add more right on top if that's what you want. You can also use Gesso to cover an old painting, ready to begin again!! Gesso smoothes out the peaks and valleys in the canvas and improves the bond between the paint and the canvas. Paint on raw canvas is more likely to crack and flake.
Priming wood means the wood doesn't suck up all the paint. If you'd like the wood to show behind the painting, give one coat of wood sealer. That will stop all of the paint from soaking into the wood. If you want to paint the entire wood area, then GESSO is the answer.
Brushes can be cleaned with soap and water after use.
