"Pos" is another way of writing "pues" which in Spanish means "Well" as in "Well I think so" (Pues pienso que sí).
"Pos así sigale a ver que saca" is going to mean "Well, keep going that way and let's see what happens" or "Well continue in those steps and let's see what happens". I'm sure you see where this is going.
A "putito" is a bad word in Spanish which basically refers to a male as "gay" so, needless to say, it is a vulgar expression.
Hope this helps!
