Spark plug interval change

On which thread I can find answer to my question, maybe some of you guys can point me there, but looking to change plugs for a 50k mile service. Here are my questions specific to my vehicle:

1. Are there two per bank? How many total?
2. Are these iridium tipped plugs?
3. MB technical or support - replacement brand w/ part #.
4. Should I replace the packs? If never been changed at 143k now, and what else should be looked into while doing this job if anything while I have it apart.
5. Brand recommend by MB NGK...??? Bosch....???

thx

I use a lot of Denso TT that work great. I would quit the OE plugs by 50-60k.
