I can see your concern about the hardwood floors, but this is just part of it. I was mortified to be bringing my son to his 9 mo checkup because of all the bumps and bruises on his little head. But his doctor just laughed and said "Oh good! Someone started pulling up! Good job buddy." My sister's doctor told her they are more concerned when they DONT see the bumps and bruises because either the baby isnt developing on track or isn't being allowed to develop properly. So don't worry about that aspect.
I just made sure he didn't pull up near the fireplace marble or anything else that was dangerous. I got a leather ottoman for a coffee table to replace my razor sharp edged table. And then I just let him do it. The earlier they pull up the more they fall I think. My son started crawling at like 7 mos I think and within a week was pulling up and cruising around the furniture. He was so unsteady he fell constantly. He would cry a little sometimes if it was a particularly big bump, but it wasn't a big deal. If you think about when you get hurt- say you bump your knee and get a bruise. Yeah, it hurts for a minute and you get irritated but then you get over it because it's just not that big a deal. Same thing for babies.
Just make sure things are secure if they can fall on him, put non-skid pads on stuff, and you can maybe get one of those jigsaw puzzle type playmats and put his activity center on it. That will work for a little while until he gets bored but by then he might be a little more steady.
Edited to add:
Don't put him in shoes to learn to stand as another poster suggested. Shoes are not good for newly developing feet. If his feet need protection, use shoes, otherwise babies learning to crawl and walk should be barefoot.
