and what about this?

3) BE Bearings-ARP Connecting Rod Bolt Set - E90/E92/E93 M3 = Do I need this too? does buying one include the entire set?

You need 1), then it's your choice to use 2) or 3). You cannot use 2) and 3)

The main difference between 2) and 3) is the OEM bolts have a *very* complicated torquing process and are single use whereas the BE-ARP just get torqued to a value.
If a shop is doing the work, getting BE-ARP bolts minimizes the possiblities for them to screw up (you think they're going to dump a oem bolt they've torqued wrong?) and helps them go faster
If you are doing the work yourself, the BE-ARP ones are worth their weight in gold.

When you do this job, there's oil dropping on you, there's stuff hanging all over the place and you're covered in plastic sheeting so you don't get caked in oil. The last thing you need is to be doing step 8 of the 9 steps PER BOLT for the OEM ones and screw up, then have to start again.
