You really might as well. Give the gestalt. Removing the identifiers.
There're no great answers to your questions. The limiting factors are basically who you are (i.e. your CV), where you at, who you know, and how much money (both personal and institutional) you have/need--so the more detailed these factors can be revealed, the more informative my response would be. Developing an independent research career does not have a very clear "track", and depends a lot on local "mentorship" (what it really means is relationships with various people who would be important in shepherding your grants). Things that work at one place don't work at another. There are also lots of differences in feasibility in terms of content of research in basic vs. applied work, etc.. Most people on this forum don't know what they are talking about. Of the people who are qualified to give you answers, we might not give you real answers if you ask us in real life, and people at the same level who have answers often have very different answers to the same scenario. The answers are also often modulated by context (i.e. is this a formal advisory meeting, some random person I met at SFN, or is this a conversation at a bar?) For example, I'll NEVER tell you in person that you should "give up" (on a research career) based on your CV if I met you in real life (don't want the reputation of not "encouraging the career development of young investigators"), but I just might on the internet. Plus, the answers are not necessarily matching up to reality (i.e. I might have a very vague sense that your career is not very hopeful in the long run, but I don't have real data to back up this intuition...and lets say multiple people you talked to give you different responses, which one do you trust? This is particularly problematic in real life, as I've noticed that the answer to your question depends a lot on whether the person who's got asked that question *wants* something from the one who was asking this question.)
Furthermore, institutions and leadership vision change constantly. So what might work right now might not work in 5 years. So any specific information (i.e. at school X, someone did Y) may or may not be applicable to you once you arrive at school X. And often there's no uniformity in the *application* of the policy, even when the policy is fairly clear. In another word, individual contracts are almost always individualized depending on various factors, most notably relationships. And when there are institutional variances in the favor of an individual (i.e. some policies are differentially enforced), this is almost NEVER revealed to people they don't trust. Nobody wants to invite an EEOC investigation. People typically downplay how much personal money they get, for example.
At some departments, even written contracts get reneged later on. Your choices become either you file a law suit or you leave. Lawsuits are typically not successful. You should think of academic contracts as sort of a "living document" LOL. Things always depend on the instantaneous marketability of your portfolio, and institutions also have extremely short memories.
You can't really trust anyone in real life, so you might as well trust people on SDN.
