Yes, inlines are the yellow or orange Offshore or Church boards. Most dive curves are based on a line diameter of .014", if you want to run an equivalent braid just look for that diameter, usually 30 or 40 lb. If you want your cranks to run deeper, there are curves using 10lb fireline or the equivalent diameter.
As far as leader on your braid, I will let someone that uses braid give their opinion. I run mono on my trolling rods, I like stretch that comes using mono. Just remember you are not holding a trolling rod, so there is no sensitivity gain using braid.
