You might want to think about the big picture first. What are your goals with firearms? Self defense? IDPA/IPSC? Hunting? Other?
While the four safety rules are universal, and trigger control and follow through too, tactics, mindset, shooting platforms, etc., change between disciplines.
Maybe I'm making this more difficult than it can be, but I would suggest learning a "system" from one person or one school of whatever you want to learn. Then when you have that doctrine and skills as a baseline, I would start to check out other techniques, tactics, etc.
Your current approach, from what I can tell, will end up being a hodge podge of skills that come from different schools, different mindsets, different missions. For example, military mindset and mission won't map well to a civilian self defense mindset and mission. There may be some overlap, but you need to be careful. Another issue to address is how much maintenance will your skills require? Again some military stuff requires thousands of rounds per week to keep their edge. Most civilians are not able to devote that much time and money to maintain those skills.
I think you could do better with a systematic approach so that you build a compatible foundation with fewer holes, I guess in a word, I am talking about "balance".
