programing Lua help

I know there's the lua site etc, but its not what I need, I want to get my head around why I need and how.

example. I look at a lua file and can see in the lines pilot/main. etc etc

and I know they relate to the graphic files in the same folder for a skin.

but lets just say I have a template which I have coloured to make for a skin.

where do I go from there? open a new lua file...................how do I get to the stage of knowing what to put?

I hope I have said this correctly, I need to find a recourse that tells me where to start to add the correct lines.

looking at others for reference is fine and I can see most of where they are but what are the false/true statements, why is there 38 lines of lua in some and only 8 in others?

sorry if this is long winded, its hard not knowing something at all :(

this for a start :)

{"civ_uh1_main_dam", 0, "uh1_main", false};

{"civ_uh1_main_dam", 2, "uh1_spec", true};

{"civ_uh1_tail_dam", 0, "uh1_tail", false};

{"civ_uh1_tail_dam", 2, "uh1_tail_spec", true};

{"civ_uh1_main", 0, "uh1_main", false};

{"civ_uh1_main", 2, "uh1_spec", true};

{"civ_uh1_tail", 0, "uh1_tail", false};

{"civ_uh1_tail", 2, "uh1_tail_spec", true};

in the folder there is only 1 file named tail, and 1 file named main, which are fuselage parts, sooo why so many in the first section of the lua

ok, 2 = default as in dmg model 0= none, same as in colours of objects trial and error
