Let him play his character, you play yours. If the game is bogged down or disrupted in some particularly eggregious way because the player is a clueless noob, THEN you might have standing to say something. Otherwise, the character is HIS to screw up in whatever way he can manage. Wait 'till you are asked for advice or assistance before heading down that mine-strewn road. However innocent and generous your intent may be, telling another player how to build and run HIS character is just not tolerable. As a player you wouldn't stand for it from your DM - why should it be any more acceptible coming from another player?
At most you might spam an offer to everyone in the game to grant them free access to your experience and knowledge and see what that gets you. I know you're only trying to be helpful, but I firmly believe that even new players would ultimately rather learn from their OWN mistakes (and SHOULD). Or better yet, that they should be allowed to do their OWN explorations of what THEY do or don't want to do or try within the game.
