My little crawler

So i have a 7 1/2 month old that is standing up on furniture and zooming around on all 4's.  He is making me think how woefully unprepared I am in having the house baby proofed.  How do people know what to do to their house to baby proof?  I feel like the books and magazines out their are for a different demographic than me.  I don't know how to balance my love of electronics with my love for my baby boy.  Does having a little guy mean that i cannot have any plugs or wires laying around for the next 7 yrs? I love him so desperately and would gladly never watch TV again if it meant that he would grow up healthy and happy...
