Dave is spot on above. Put in a few extra psi over the sticker numbers, and don't obsess over it at first. You'll have enough to focus on already without worrying about your tires. Just make sure you stay below the max pressure listed on the side of the tire for safety reasons.
There are little triangles somewhere near the edges of your tread. The wear on you tires should go
roughly to those triangles. If that triangle is getting chewed - more pressure. Not there? Drop a few psi. Note this is a very rough dial in, and contingent on not overdriving the tires or you'll get bad readings. Some people use chalk / shoe polish on the corner of the tread to better see how far the tire is rolling over. I got pretty lucky with my first guess when I switched brands:
Once you get more comfortable, you can tweak. Remember there is a "best" pressure for each surface on each day. Either more or less will reduce grip. But tires are also part of the suspension, easily tunable springs. More pressure acts like more spring, less pressure is like a softer spring. Sometimes a small pressure change can tweak the balance to do some good.
