[Q] Need help with updating

It's been a very long time since I last updated my HTC One S, and recently I was going to do an update. I'm not quite sure where to start because I still have my old roms and recovery flashed. I tried searching through various forums but it seems like most of the posts are at least updated to a more recent HBoot. I'm a complete noob when it comes to custom flashing roms and whatnot and was hoping someone might be able to point me in the right direction of what order to update my phone in.

As for my phone's versions:

HBoot 1.06.0000
Android Version 4.0.3
HTC Sense 4.0
ROM: LeeDrOiD One Supreve V2.0.0
Recovery: ClockworkMod Recovery v5.8.1.5
Kernel: Stock as far as I know

Any help is appreciated! And please let me know if additional information is required.
