Here are my questions:

-How to get some extra coin fast

-How to level smithing (Don't say make a crapload of armor because I can't afford or achieve all the materials)

-Where to get fortify smithing armor and potions

-What level to stop using my claws

-When I stop using my claws, what dagger should I get? (Of equal or greater damage)

-How to get your theft perks up fast (sneaking, lockpicking, etc.)

-What level are you capable of entering dwarven ruins?

-How to enter the dark brotherhood?

-What level is it safe to start doing Markarth Quests?

-Looting dungeons.

-Smithing jewelry.

-Self-explanatory. Buy them from the potion shops, loot mage dungeons, or level alchemy and loot the ingredients to make your own.

-Level 1. The moment you acquire a melee weapon.

-Self-explanatory. The most powerful dagger you can acquire.

-Self-explanatory. You level them fastest by just using them.

-Level 10

-Talk to the Inn Keeper in Riverwood, the first town in the game. Ask him what rumors he has heard until he mentions them. Then go to Windhelm using the objective pointer to find the boy and talk to him to get a quest to kill someone. The rest of it is self-explanatory.

-Level 10.

Actually your Claws in the beginning are your best weapon. 22 Damage is much better than 9.

Of course leveling some combat skill might be necessary.

This is pretty resourceful accept for the fact that claws do 15 damage and are faster and stronger than almost every early-game melee weapon.
