Hi, Tim.
1. Doomstones are not marked on map. They give you Greater Powers, so you can use them once a day and after 24 hours you can use them again.
2. Only way to restore magicka with Atronach Birthsign (I suppose you meant Birthsign) are potions, Velkynd Stones, Ayleid Wells and blessings from shrines. If you are going for Atronach Birthsign I would say that Alchemy is your best bet.
3. Stones are separate from Birthsigns and you can have only one. But lot of stones have restrictions, mostly certain amount of Fame.
4. You should be able to hit 100% Magic Resist, but I´m not sure if it negates all damage from incoming spells. You can take look at my Antimage where I talked about synergy between Reflect, Resis and Absorb.
5. To create your own spell you already must have variation of that spell in your Spell "Book". Say you want to create spell that does Fire, Frost and Lighting damage at the same time, you must know all three spells. Enchantments from weapons doesn´t count for Spellmaking.
And sorry for late response. I hope this will help you :)
