victus amore eius - 'victus' is a passive participle (from vinco); 'amore' is ablative of means, a common construction with a passive verb - "conquered by love". 'eius' is an objective genitive. So: "conquered by love for her"
For the other underlined bits, I think you're confusing several words:
mora, -ae: "delay"
mors, mortis (f): "death"
mos, moris (m): "custom, manner"
Look again at the forms and I think you'll find they make sense.
