Engineering is the best combined with Mining. If you level your Engineering with Mining, you will save a lot of gold. Specially when you have to use Mithril and Thorium, because they aren't hard to find.

It is important to buy a [Gnomish Army Knife] from the Auction House before you start. It is used to replace Gyromatic Micro-Adjustor, Arclight Spanner and Blacksmith Hammer. If you can't afford to buy one, you will have to make a Gyromatic Micro-Adjustor and Arclight Spanner while you level your Engineering and you also need to buy a Blacksmith Hammer from the Blacksmith supply vendor, it's near your trainer.
First, visit any trainer in the main cities of old Azeroth - just ask a guard, and learn Apprentice Engineering.

Engineering has the option at skill level 200 to specialize in Gnomish or Goblin Engineering. The main difference between both sides is the location of their respective teleporters and the ability of their trinkets. Some items require a specific specialization to use, while other items are crafted by one specialization but are usable by any engineer. Fortunately, most recipes that are crafted by one Specialization can be worn by both.
