Can someone help me on monitor calibration?

I just recently calibrated my monitor, and found out one of my previous graphic design had ugly stripes going out from the center on the background. Before the monitor was calibrated, I remember the background being pure black. Can someone with a professionally calibrated monitor help determine if my monitor needs adjusting?

Photos in Photoshop are too red..monitor calibration necessary?

I’m editing photos from my wedding and all of them have more of a red tint to them then I would like. They were not shot with a warm filter, and were done by a pro.
I’m not sure if I need monitor calibration because the photos look fine in the thumbnail preview, but as soon as I get them into photoshop, it appears all of them need less red.
This is causing my prints to come out wrong..any advice?
