The first steps is to make a plan. Any plan(for the most part) is better than no plan at all. Follow it and adjust as you go. Absorb all the knowledge you can. Add to your stockpile as your budget allows and go from there. Remember that a lot of prepppers have more money than brains sometimes and not everybody has unlimited funds to use on stockpiling.
Great start to long term storage for a good price! I like your first choices very much for cost and ease of use. My best friend used to bring a ketchup sandwhich to school on a regular basis and would have loved to have a bowl of rice and beans.
It's a logical assumption that you have already added to your normal food suppy of canned and packaged food and are doing rotation, most people start there, and this is a very good second step. You are going to put a lot of meals back really easy.
As you move forward these are good to have...
Freeze dried meat in #10 cans.
Wonder Junior grinder.
Cold pressed olive oil.
Salt and unground pepper plus spices that you like.
