Well there's efficient leveling, which means raising a skill governed by a certain attribute I.e. Raising marksman 10 times in a level will give you a +5 multiplier to agility when u level up. Best to do that though from level 1.
To be honest though you don't need high attributes and skills to be good at the game, as long as your enjoying yourself and not having trouble killing things, you don't have to really worry about those things.
Regarding getting 1000+ magicka I don't think that's possible not in vanilla I don't think anyway.
