So in order to get the booster/implant slots you must recruit a higher tier character. But you should rush for a full GREEN team then use blue or green level 2 or 3 implants and get through at least half of the story.

No, they only get promoted to a certain level.
Beyond that you currently need to purchase a new character.
Like the poster above you said, there are levels.
The devs made it known they are planning to bring in "Boot Camps" that will allow you to boost your current characters so they can continue to level.
I purchased a recruit.
But how do I change a team member with the purchased recruit?
I don't see any where to click or drag.
