Hello first of im new to warmachine/hordes and have only one model wich is Avatar of Menoth and have warmachine prime remix book, but have never seen it played, well on you tube some battle reps, i have read allot here on battle college and privateer forums and came to the conclusion i want to use Grim Angus with the troll impalers and alten ashley once i reach 500 points, i'm trying to get some warhammer friends into this game, and i probably will

I've just ordered a battle box of the troll bloods since the impalers are in there and the axer seems realy nice as well as far as battlecollege tells me
Now here's my first list
Grim Angus
Troll Axer
Troll Impaler
Troll Impaler
Krielstone Bearer and Stone Scribes (6)
Stone Scribe Elder
UA
Trollkin Longriders (3)
Alten Ashley
Swamp Gobbers
This comes down to 500 points exactly
Also a couple of questions
In MKII you cant have random numbers of troops right? i usualy see you have to max the units but recently i've also read you can have the minimum as well, is this true?
Can have either 6 or 10 Kriel warriors then no in between?
And do i need to buy a hordes book or will the book in the battlebox + warmachine prime remix book be enough?
