I wouldn't suggest too much tweaking on your own. The gals who have responded are all experienced riders. If you've never ridden before, you will have to expect a certain amount of soreness as your butt toughens up. Even the pros go through this at the beginning of the season if they have taken the winter off.

First step I would suggest is to take the bike back to the shop to have the saddle set up right for you. Then take it out on the road for short rides. And don't stop to change the position every few minutes. Leave it alone, do a short ride, and give yourself an overnight rest to recover. If you feel you need to adjust, do it the next day before you ride. If you keep on changing mid-ride, and you have no point of reference because you have never ridden before, you will just end up confused. So as you experiment, ask questions.

You shouldn't be sore in the soft-tissue. If the store sets you up & you hurt up front, try something else. The sit bones will get used to a saddle, soft-tissue will not.

And if you must tweak on your own, you tilt the nose down to alleviate pressure on the soft-tissue, tilt it up to ease up on the sit bones. Please tread carefully here. Dead-level is considered neutral and a good place to start. If you start tilting, you will put pressure somewhere else, too much tilt down & your arms & shoulders might start hurting.
