I did the same, deloaded big time and started 5x5 from scratch.
My personal 1PR's right now:
SQ: 155 kg / 342 lbs
BP: 110 kg / 242 lbs
DL: 155 kg / 342 lbs
MP: 65 kg / 144 lbs
My goals are very similar to your best lifts for the end of this year.
Thanks for the advice, it is always good to know that one does not walk alone.
