In regards to models which would you say im best off going with in terms of my non existent experiance

?
It depends on what the art style will be. Of course it also depends on what the game engine supports.
Remember that you don't have to create complex models in order to start making your game. You can start with very simple placeholder assets (a simple piece of geometry or a simplified version of a humanoid etc.) or use assets that may be provided with the engine (quite a few engines do this).
Here's a video by Almost Human Games, the Finnish developer that made
Legend Of Grimrock. It shows exactly what I mean.
You might want to look into making a 2D game with sprite graphics. The threshold to making one is lower and should be a nice introduction to making games.
Where do i start. I cant even work out what i need to download. Its all very confusing.
Have you chosen an engine already? If not, then take a look at some engines. If you find an engine or several that interest you, then start looking through their documentation. See what kind of workflow and tools they have. Work your way through tutorials for some basic stuff like creating maps and scripting things. Once you think you have a good enough grasp for how to script things, then you should start trying to implement some ideas of your own.
One way to learn the general aspects of scripting is by modding games. While the scripting language may differ from the one in the engine you'd like to create your game in, it will teach you how to think when programming.
I'm currently in the process of learning Papyrus (scripting language in Skyrim's Creation Kit) in order to implement some ideas on making the player character's past influence his/her skills to varying degrees. Skills and perks are affected by the chosen profession and age. Age also affects health and stamina. So while a character may be more skilled when old, he/she is also physically more vulnerable. Might even look into implementing disease resistance based on age. I've been annoyed by the fact that the player starts out with skills and stats that are only affected by race.
Some engines won't have been around for long enough for lots of tutorials to have been made. Some won't have many tutorials despite being in development for years (I'm looking at you FIFE). For fairly obvious reasons engines like UDK, Unity and CryEngine 2/3 have loads of tutorials.
Also could you link me to the tut for the epic games udk (or do you think that engine will be too much for me?)
Here's the tutorial.
You might also want to take a look at
Game Editor as well.
EDIT:
GameMaker Lite is also an option. There are some restrictions, but you might be able to get the results you want.
