My plan is know the language then learn how to do game programming with it and then make a simple game then make my way up from that.

Sounds good.

My plan overall is to start my own indie company

So make games and sell them. All alone or within an indie team? Its important because if you wanna do it all alone, you will need to be a good programmer, artist, designer, PR guy, marketing guy, etc. (Of course you can buy art, music, hire a marketing guy ...but you get the point:)). In a small team you dont need all of that.

my own indie company but i want as much experience as i can get

If you dont want to work for a company then you dont need "experience"(maybe you will change your mind later, ...but the Uni will give you enough experience to get an IT job, so no problem). You need to make games.

What are your goals? Be an indie(as a hobby), be an indie and make money, be part of an indie team/small studio, or work for a big company?

Which language: search the "For beginners" forum for threads. Every other day someone asks this question.

If you know Java and C# already then you could start learning C then C++. If you want to.

Also i would really like it if someone told me about a good book to start with as well and also if they could direct me the right way

Depends on what way you want to go. Indie/small team/big studio

I don't care how long it takes because i have a lot of free time and i would really like to do something because i'm always bored

If you are bored because you dont have to work yet then better make up your mind soon;)

If you want to develop for Android, go with Java.  If you want to develop for iOS, go with Objective C.  If you want to develop for PC or console or any other machine that can support an MMORPG, go with C++.  If you want to make a D&D Character Generator or something, then use C#.

You can write most of your code in C/C++ for droid and IOS games now.

"C# is for pansies who wish they could program."

...apply some self-moderation to your posts.

Thanks. I was not precise. ....my English. I draw a polygon with the mouse. Which is practically a closed polyline/line-strip. Sometimes I need to reorder the points so the polygon is always "drawn" the same direction. (I dont draw the polygon directly, I build it up from triangles. The triangles are drawn CCW.) Should the points of the polygon ordered CW or CCW? 

Simplest 3D graphics: Proteus

The physics are 2D (despite the heightmap), even square objects like the house are circles in the physics engine:) The game eats half of my CPU. If it would be written in the proper way it should only use 10-20%. Despite of this this its a great game.

(I dont think you meant as simple as Wolf3D, or Doom1)

More simple 3D:

DuBlox

Ranger

Complex 2D:

Limbo,

Luminesca,

Knytt Underground,

Feist

If you are just "trying to get a sense" then you shouldn start with an engine, ....or with a 3D game. Almost every 3D has simpler 2D versions. (Minecraft -> Terraria)
