Hey fudal78,
Welcome to da Waaaugh!!
First things things first.
1. Yes, Orks are typically most effective when the main force is Boyz with an occasional side order of Gretchin (mainly used for standing on Objectives)!!
The only other real Troops that Orks can use are Nobs or Nob Bikers if you have a Warboss or two. Nobs are good as well, but due to everyone loading them up with unique equipment load-outs to make them effective...even a small unit can become quite expensive.
Because of their low LD and initiative, you Need as many Boyz as you can get!! Unless you're loading up some Trukks, I would never take less than 20x Boys per squad. Shoota boyz are generally considered more effective than regular Sluggas because they get Assault 2 S4 Weapons. Even at BS 2, you're going to get a lot of 5+ when you roll 40+ dice, so they more options than just moving and assaulting.
No matter what size of Boyz squad you have, you ALWAYS, ALWAYS want to have a Nob with a PowerKlaw in the mix. Aside from a few specialized units and transports, the entire Ork Codex revolves around various PK delivery systems. Boyz are basically cannon-fodder to get that Nob with the Nasty PK into battle.
2. Aside from Boyz, you will definitely want Lootas. With 48" range and d3 S7 AP4 shots, you can do some serious damage to light vehicles and high toughness units. Kommandos can also be effective with Snikrot so your on the right track there.
3. You are also correct in assuming that Orks don't rely that much on Heavy Support. Killa Kans and Looted Wagons are probably the main Offensive units in Heavy Support. Battlewagons are great transports and can make effective offensive units when loaded up with 20x Shoota Boyz. Deffrollas and Big Shootas are also good options.
Long story short, you seem to be on the right track for starting an Ork army, just make sure you get Nobs with PK in every unit that can possibley take one!
