ah found the answer to the first question myself^^ wiki quote:

"Swordsmanship

Excalibur has improved mastery in the Tenno art of the blade, receiving +10% attack speed and +10% damage when dealing melee attacks (including via Exalted Blade) while wielding the following weapons: Bonuses are additive to mods such as Pressure Point and Fury."
 * Longswords, such as the Skana.
 * Dual swords, such as the Dual Skana.
 * Nikanas, such as the Dragon Nikana.

so this means: not only melee mods affect exalted, but also the equiped weapon itself (!) concerning its weapon-type.
