Are you squatting heavy 3x a week? If you are its time to move on to the advanced novice template. For your deadlift, are you using chalk? If not, you should be. Do you use a belt? If not, it's probably time to start looking for one.
But yeah, it looks like it's time for a reset. You could probably keep pushing for another 10-15 lbs, but I don't think it would be useful in the mid to long run. I'd drop down to 245 on the squat, and 275 on the deadlift. These are probably a larger reset than is absolutely necessary, but it will help you in the long run. Form will deteriorate on the high end if you're a novice/intermediate lifter. As long as it's not wretched, you're probably ok.
