Hey abnk,
In general, when you have pain like this it's better to keep training at tolerable weights than to take off from training or reduce the weights all the way down to the bar. It has been my experience when people encounter pain or something noxious/uncomfortable they tend to use one of two strategies. They either avoid the pain or push through the pain. I think the ideal strategy is in the middle and it is to nudge the pain. It is important to note that tendons do not heal like a cut. You will probably not be able to wait this out. The process of getting better is not linear. The rehab process has ups and downs, with good days and bad days. If you have a bad day it does not restart the process.
I would resume deadlifts and squats at a tolerable weight and gradually build them up over time. I would probably also add in calf raises and gradually build them up too. If you are a runner or are doing other activity that is loading your Achilles, the load from that activity should be graded and built back up over time as well. Exactly how you should do these things is beyond the scope of this board and more in consult territory. As a general strategy though the above would be a good approach.
