Encode using Nero to LAME MP3

Hi
Can some one advise the settings to use in Nero using the encoding of files to Poer Pack LAME MP3 encoder?

I want the best qulaity under this encoding so currently have:
Encoding quality at “0”
VBR rate - “0”
Channel mode “joint stereo”

I use classical mostly - or musicals

Are these setting correct for me??

TIA
