Need more info.
What I can tell you from the info I have:
1) You need to be patient. If 355 is your 1RM then you need to be training with 225-335. It sounds like you have reached a plateau which means you aren't going to get anywhere if you just keep maxing with 355.
2) 405 is a good goal but you will go above and beyond that if you stick to a solid program and train diligently. I reccomend 5/3/1 because it's simple. A moron could do it.. and many have. That doesn't mean it's not effective.
3) Get a good belt, Learn proper form, When training make every rep count.
