If the pins are 0.5mm or finer, you're better off not having solder mask.

Have a look in section 3.7.2 of this doc:

As far as soldering it goes, I'd go for lots of liquid flux.

Mike, welcome to the group. You're certainly not coming across as a
newbie! Hope you have fun here. If you get stuck over the next few
