Hi Matt: I would focus TPE on Puck Handling, Scoring and Defence with secondary focus on Passing, Checking, Skating and Strength. I really wouldn't waste my time on the other attributes as they're less of a factor.
Focus on the first three and try to get them to at least 80 + and then work on the other four attributes, then your player will be even better offensively.
Try to earn your max 12 capped TPE each week, along any available uncapped TPE you can earn here.
As for the reputation question, Idk but get involved in the topics here.
Nice to meet you!
