All 70's suit = 350 Resists
4 pieces of barbed at 62 resists a piece = 248
Difference 102
Necklace 30
Earrings 30 ( 50 if you use night eyes, 60 if you use Folded Steel)
Left to Imbue
12 if you use folded Steel
42 if you use Earrings
22 if you use Night Eyes
Your Best bet for simplicity is to use the Folded Steel and the Orny, It would be possible to hit all 70's without imbuing any resists.
If you don't use the orny then craft necklaces with 1 resists at minimum. If you don't know what the minimums are, craft a non exceptional one and those are the minimum for each category. Then Craft 20 Blanks of each other slot of armor, and use the Armor COmbiner and bam, you have a suit.
