Firs of all, sorry for the english, not my main language ok, first time doing this, i realy need a answer to this, Mark help me here for god's sake ( or if someone know where the answer is)

I know that you can't Use Vital Strike with Kineticist Kinetic Blast, but with infusion like Kintic Blade/Whip, that's says you create a weapon, and "as part of an attack action, a charge action, or a full-attack action in order to make melee attacks with your kinetic blade."
Would it be possible to use it like that, as now i "holding" a weapon ?

And while grappled, do i need to make a concentration check to attack with a light blade create by Kinetic Blade, i know that Kinetic Blast is (SP), But in infusions say (SU), and i'm holding a weapon, so i realy need to make this check?

And the last one, the infusion Wall says "The wall appears within 30 feet and can be either up to 10 feet high and up to 120 feet long or up to 20 feet high and up to 60 feet long." but there is no shape, so can i shape the way i like as long i don't bypass thoses limits, or it's need to be a straight line like my GM claims to say ?

Please i rly need a answer to this, it's been like 2 weeks that me and my GM are arguing about these, don't let those questions die here...
