Congrats, and also, god help you lol. I started off purchasing a 1/6 Christopher Reeve Superman figure years ago, and swore to never purchase another. Ten years, and 30 or 40 figures later, I'm still saying to myself "Ok... THIS is my last figure, for real this time". It can become an addictive hobby rather quickly, and get out of hand if you don't set reasonable boundaries for yourself, your living space, and most importantly, your wallet.
Majority of people store their figures behind glass, and the Ikea Detolf was a very popular, and affordable solution for display. However, I hear it is being discontinued after all these years. But a glass display will prevent a steep nosedive to the ground, or prevent Murphy from becoming your cat's favourite new chew toy. As for maintenance, just dusting mainly. Some people have had bad luck with rubber components deteriorating over time, but that can be exacerbated by environment (temp, humidity, etc). I've had my original Robo in all kinds of poses, and there have been been no issues with rubber deteriorating at the joints.
As for stands, the waist grabber that comes with this Robocop is a lot more secure than the old crotch grabber from the initial release. That said, the OCP logo is from R3 I believe, so if you're an R1 purist you may want to think about a custom stand (ebay/etsy) or even a custom diorama stand can be fun?
