At this point I'm basically "baby proofed" 1 room upstairs and 1 downstairs. In his room (upstairs) I just put cords behind furniture, outlet covers, and put a little thing on the bottom drawer that keeps it from closing all the way (its designed for doors) so he doesn't smash his fingers. In the living room we have a big gate (more to keep our very large dog out) to keep him in there, and pretty much everything picked up but his toys and things that are safe for him. We took out the wobbly end tables for now so there is no chance of tippage. Anywhere else in the house I just watch him close, and I usually don't let him "loose" in the kitchen. He has a walker that he plays in in there.
I'd like to put cabinet locks on the under the sink cabinet.. but that's about it.
