Sounds like some good plans on the health side of things, I think seeing a doctor is definitely a priority sooner rather than later, throwing up blood is not something to mess around with.
What I don't see in your list is any sort of "sobriety specific" plans on how to actually deal with your addiction. Things like "go to an AA meeting" or "see an addictions counselor" or "spend time reading and posting on SR" or "read some AVRT materials" would fit into that category. Perhaps you could consider carving out some time of each day to specifically work on those things?
And regarding your last comment - everyone is different of course but it's not usually recommended to start up new relationships early in sobriety. We generally need to take care of ourselves first before having the time/energy to commit to a relationship.
