It's a tough process of learning how to lift everything even. Especially for someone who isn't used to it. Natural tendancies will make you try to "horse" the weight up instead of pulling(deads) or pushing (squats). Something you should keep in mind is that the weight isn't really an issue at this point. A word of advice without seeing you lift would be to always imagine you are pushing your feet through the floor. Not pulling the weight through your body.
Yes,rippetoe and louie simmons both. Simmons transformed a garage looking building into the strongest gym in the US,which happens to be in columbus. Dave Tate is another guy you can learn a lot of great info from on youtube.
I know you won't want to do this,but at some point in time it would be a great asset to film yourself doing those lifts. Once you educate yourself on how the lift is supposed to be done it's a lot easier to watch yourself lift and pick apart things you'd like to do differently. A lot of my vids are in a college gym,and it looked weird as hell,but I care more about bettering myself,then what someone else thinks.
For what it's worth..Years ago I talked to one of the top heavyweight deadlifters in the world,and we were discussing form on squats and deads..His exact words were " I have to learn how to do them every single time I lift." It was a short convo but really put things into perspective.
