I have a junior point guard that is a 51 ATH,  64 SPD, 48 DEF, 1 LP, 36 PER, 65 BH, 61 P his IQ's are both B+, FT B-. My question is should I give him more distro to try to get him to the line and also get his hands on the ball more to dish it for assists. Will increasing distro help in those aspects? Will it be counter productive? Maybe causing more TO's?

Well, increasing distro will reduce his assists, at least.  Don't worry too much about assists.  They're assigned after the basket and reflect each individual's passing rating relative to his teammates', more than anything else.
