If it lean bogs then richen to the top end a little at a time until it comes right.

With the long needle LSN's this needle controls the fuel delivery from idle up to around 90% WOT, so yes, most of the bottom and mid range tuning is done with the LSN.

Don't worry about temp. Tuning to a temperature is not a good idea.
Tune for nice power with good smoke. If the engine is performing well and not bogging down or going flat at WOT then it is in a happy place temp wise - whatever that particular temp may be. All motors will be a little different (due to fuel, plug, pipe, even driver style), so tuning by matching the temps of someone else's motor is a recipe for trouble.
Generally most motors will run between 95C - 115C at a race tune, but some can be higher and still be totally happy.
