No attribute points in magicka, all in health .. but I'm a vampire so I need to watch my health. I almost never run out of magicka.
I run a seducer 5/ willow's path 3 crafted gear set with health buff enchants and an absorb health chant on my staff
I have a two ring / necklace set ... I can't remember off hand what the name of the set it
Gear sets are based on what you have access to and what buffs you want, eg magicka, spell damage, spell crit, health etc.
You may not need to ... depends on if you run out of magicka. I don't know the theory crafting and whether more magicka makes a significant difference to how hard your spells hit. Perhaps Tamriel Foundry will help.
If you want to solo world bosses you will need survivability but balance that if more magicka actually helps you kill them faster.
