Hold your horses son 70 Entity pack could be a little to much at first try like making 1 model at a time and try to do your best!
And kraven dosent use milkshape he uses somthing called blender wich you get a UV-Mapper with(i think)
And cant you just use the Texture cordinator? at least for some basic models?
Weapons is another case, you will need to animate.
Wich is really hard and then you would have to use another program for importing the animation.... basicly try to make somthing easy at first, like som crates or somthing or go pro like i did and make a half assed gun.(no really i looked fine for my first model)
PAINT.net is free google it.
google is your freind...
