Are you trying to get root? If so then yes, stop at 893 which is where you grab root and you will be on the update path. If you want more info on rooting speak up, I will leave that info out because I get the impression you don't care if you have root. You can then wait for the OTA, or you can download it from these forums and do it now.
If you don't want root, your solution is very simple. Download the 901 to 902 update and apply it in recovery mode. It will take you 15 minutes tops and you will be up to date and good to go. It is in post 38 of the thread below. That is the one I used to get from 901 to 902. If you don't want root, just do it that way. Easy, and for sure back on track for the next update whenever that is.

Again, post 38 in the thread above to go from 901 to 902. The zip file should be about 25 MB. If you get one that is about 56 MB that is the wrong one for your situation.
