I myself have never raided (at a competitive level) on rogue, I have however on hunter, and Tauna has great - however it does take tweaking per raid boss
I suggest running the raid with a pug to test things, when you find a good setting that works save it as "<Boss Name>.xml" then you can easily load it next time.
Generally each boss will need a setting if you want to perform optimally.
Each raid blizzard releases they have a patchwerk style boss, start on that - its a good basis to get your general settings right.
Once you have done that you can go one step further and write custom plugins that will auto-switch targets for you, use CD's etc at the times you like - this isnt needed but it does help you reach top dps rankings (100%) instead of 98%.
There are loads of discussions on Tanuha's rogue sites on how to best set it up for raiding, but one persons setting wont work for every person, its trial and error and practice.
Keep in mind - dps can fluctuate - as an example on my DK at present in crappy dps gear I can do 40k dps (single target) if i focus 100% and dont stuff up my movement / targeting once, however if i slack i do 25k dps - yet its exactly the same rotation done by the bot.
