You can buy it at Anvil's Mage Guild.
there are soul trap spells you can purchase, cast the spell on an enemy and kill them while the spell is still active, but you need to have a soul gem in your inventory to hold the souls you capture. There are also soul trap staffs if you are too sucky to use the spells.
yes but you have to buy a spell from a spell trader
most alchemy shops will sell them. try the imperial city market district.
Just buy a Cure disease potion, eat mandrake or get the cure disease spell.
If its magic as in spells you buy them from spell vendors. If you mean magic as in magicka you upgrade the corresponding thing (forgot the name) when you level up.
