My advice was tailored to a more strength oriented system. You get what you train for, if you train for mass you get mass and if you train for strength you get strength. When you are in the middle ground you get the middle ground, sooner or later you have to take one fork in the road

Running will affect your gains if you're not eating enough calories to account for the ones you are burning. If you maintain a calorie surplus it shouldn't hurt you. By the same token you shouldn't be running for 3 hours a day or anything.
There are journals on here that are tailored towards strength training. I'm not saying you should grab one and follow it, but you should notice a general trend. Low reps with heavy weights and high intensities, with higher rep work to compliment it. High rep work is always 'secondary' to the low rep work.
There are also quite a few articles and posts based on strength training. Madcow's Strength vs Hypertrophy training (I think that is the name, I can never remember tho) is very good.
I could write quite a few pages on strength training, but trust me it is much better for you to go and read it for yourself and develop your own knowledge base. There will always be someone to answer questions you come across, so its not like your being tossed in blindly to figure it all out.
