First of all, Sneaking will work best if you have Sneak as a skill. You also need no armour or light armour.
Otherwise its like an Atronach trying to sneak through Chorrol in the middle of the day.
On conjuration, yes you can summon blades and swords, and I think they level with you (they are also Daedric, so good against undead), but to get Swords, and Bows you have to pay a visit to Chorrol or Raminus Pole -- and they will charge you alot, also you will need a Conjuration of at least 50, usually 75............So not good in the short term. Get a iron bow.
Make sure you increase Strenght stat when you level as much as possible, if you train Block and Blade alot that will help. Alteration? Use it for Shield spells, but its worthless if you are going to use HeavyArmour.
You said about making potions, but you have no alchemy skill. Swap out Restoration/Alteration for Alchemy.
Then you should be fine.....phew.
