No sweat, we answer what we may, hehe.
1) No unit name will refere to Ar-Pharazon, no, because Sauron hated Númenor and Ar-Pharazon most of all.
That ties together with that there will be a Temple Guards-unit, yes, but it do not concern Melkor/Morgoth.
Hmm, easiest to make a little history lesson of this I guess.
When Sauron became the new Dark Lord, he implemented himself as a god, and himself only;
During the Second Age Sauron came to hate Númenor, for many real and perceived reasons.
When Ar-Pharazon came to Middle-earth with his host in 3261, he humiliated Sauron (naturally) and earned Sauron's personal hatred. Sauron did accept to have Numenoreans as servants (more sensible he was than his former master would been in such a situation), but Númenor's destruction and Ar-Pharazon's death was his big goal - otherwise he could had kept Númenor and Ar-Pharazon as his servants to use them to rule Middle-earth. That would been smart, but he did not because of his hatred.
As was seen later in the Third Age, even in Gondor that was a common view that Ar-Pharazon shamed the Dark Lord, and Sauron would accept no recognition of the old king:
While Sauron was in Númenor he started to preach the gospel of Melkor as we all know:
But it was not because Sauron led a religion to worship the former Dark Lord, but because it was the best way for himself to gain power. He could not call himself a god, because Ar-Pharazon had defeated him, but he could gain influence and power in the kingdom by acting as a prophet of 'another':
But even on Númenor, in time Sauron was happy to become the center of worship as a god himself.
The BNs were, we can guess, proud of Ar-Pharazon and the might of their people at their peak [of power], but I can not fathom Sauron to ever approve of them putting it on display, or brag with the name of his personal enemy.
Also, there will be a Temple Guard, the elite unit among BNs, but the religion of the evil factions is called 'Followers of Sauron' as they worship him, not Melkor, and the temples will refere to Sauron.
2) No, not in visuals. Their greater height is accounted for in unit stats, but we won't bother with small height differences that would require
massive labour to fix for no actual gain
