With those training maxes I would strongly recommend switching to a linear progression style program for just a little while, then going back to 5/3/1 once that stalls.
5/3/1 is a great program, but the progression is really slow for newer lifters who have the potential to make really rapid gains for the first 3-4 months or so. Until you reach a certain point, it's very easy to add weight to your lifts every single workout. Programs like Starting Strength or 5x5 can take the average male from a 135 back squat to 275-315 or more pretty reliably in 12-16 weeks (genetics, determination, willingness to gain bodyweight, etc. will play a role).
Once you can no longer add 5lbs to the bar each workout, switching to more a more complex loading scheme like 5/3/1 is a great way to keep making progress, albeit a little slower.
