Welcome back
If I may suggest, don't "wait" to develop your SS skill set--dig into those books now and start practicing the skills you want to use in your everyday life
I know it's not gardening season, and it sounds like you are already well-versed in poultry-keeping, but I'm sure there are things on your list that you can start doing right away. Which books have you bought, and which are on your wish list?
The pressure canner is a great place to start, jump in with both feet and try a simple recipe like plain pinto beans. If you've done water bath canning in the past, it's not hugely different--just a different processing method and timing. Read the manual that came with your canner and use a recipe from that booklet the first time around. Then once you have a handle on how it works, you can pressure can just about anything (except, apparently, pureed squash/pumpkin

) Lots of people on here are into pressure canning and we have tons of recipes to share, so don't be shy about asking any questions!
When you say "seed bank", is this one of those "prepper" type kits, or your own self-gathered/purchased garden seeds ready for spring? Are you a gardener, or are you just starting out? Some seeds will remain viable for a long time, others have a limited storage time--so you need to plant them every year, enjoy the food, and save seeds for next year. Some plants are easy, some are more difficult, and some depend on your local conditions--so some plants you are used to growing in OK may drive you crazy when you try to grow them in CO because the climate is so different.
