The maximum damage reduction you can obtain in the game is with level 25 TB, in-game powerup and Vest mastery level 4.

99.9% is the maximum defence on all of the damage traits, and you need over 21500 on any to obtain the full defence.

Can't remember for alloy/aug rewards on mobile, you'd have a look around the wiki for that, but for levels, the maximum on any character on any platform is 100, however it is possbile to obtain 108 skills points with the bonus 8 through the augment rewards.
