I think Razor has patches for the base game, or at least the cracks for them. I just update normally, with the launcher, and my Arr'd version is from Razor (Except WA and HELS those where Arr'd from different people as far as I know). Make sure when you patch that cracked files are replaced by originals or it won't work.
Why use craked exes or craked patches? If you are pirating the game, install it normally without the EA download manager and then patch manually. Then when you're ready to run, make sure you have awesomemod installed. No cracked EXEs or custom patches necessary. This way you can stay as up-to-date as the current AM allows.
EDIT: to clarify, as long as you have the ISO and serial... just install and patch everything as if you had the legit game, but don't use the launcher. Start the game from the /Game/Bin/TS3EP01.exe or TS3SP01.exe... etc. You can even still use the launcher to install sims3packs and what not
