First, I am not an expert. But, here goes.
Having the sag set correctly for your weight is important for the bike to work it's best. To soft or to stiff is not good. Having said that, many of us have a difficult time knowing what difference it makes.
The harder you push your bike, the more difference this makes. Some people like more sag than others, so having (some) extra sag may be ok for you.
You can also move the forks up in the triple clamps to compensate for extra sag. The more the forks are raised, the 'twichier' the bike becomes. It tends to carve sharper corners, but also looses straight line stability.
Adjusting the clickers really does nothing for seat height. The clickers adjust compression and rebound when the forks/shock is compressed (as in riding it). The clickers should be adjusted to suit your style and needs. You don't want the bike to bottom out hard, but you also do not want it deflecting off of rocks, roots, bumps in corners, etc.
Now, I have a friend who is height impaired. He uses a log or rock to stand on to start the bike. He then slides his butt to the left or right to steady the bike for take off. If he falls or stalls after that, he looks for something to stand on to help out. We never ride alone, so if nothing is available, I will help him out.
