Yes, of course they did
I think this is how the Professor himself would respond to your criticisms:
[I]f we dare to attempt to enter the mind of the Elder King, assigning motives and finding faults, there are things to remember before we deliver a judgement. Manwë was the spirit of greatest wisdom and prudence in Arda. He is represented as having had the greatest knowledge of the Music, as a whole, possessed by any one finite mind; and he alone of all persons or minds in that time is represented as having the power of direct recourse to and communication with Eru. He must have grasped with great clarity what even we may perceive dimly: that it was the essential mode of the process of 'history' in Arda that evil should constantly arise, and that out of it new good should constantly come.

It seems a mistake to apply our notions of right action to characters who
- Were written decades ago, when Tolkien's views on morality need not mesh with our modern ones
- Are celestial beings with an element of precognitive ability
But with regard to your specific accusations:
The Valar didn't try to find or protect Men
How? Bringing them to Aman would have caused more problems than it solved, and open war against Morgoth would have been intensely destructive; even the earliest wars caused untold destruction on the world.
With both of the Children now awake, conflict on that scale is too risky.
And, in fact, the Valar did take action to protect men; that was their prime motivation for creating the Sun and the Moon:
[I]t is said indeed that, even as the Valar made war upon Melkor for the sake of the Quendi1, so now for that time they forbore for the sake of the Hildor, the Aftercomers, the younger Children of Ilúvatar. For so grievous had been the hurts of Middle-earth in the war upon Utumno that the Valar feared lest even worse should now befall; whereas the Hildor should be mortal, and weaker than the Quendi to withstand fear and tumult. Moreover it was not revealed to Manwë where the beginning of Men should be, north, south, or east. Therefore the Valar sent forth light

The Valar were quite unfair to poor Fëanor
This is one of those situations where my two points above really come to bear:
From the perspective of the Valar, they were doing the right thing:
The closing of Valinor against the rebel Noldor (who left it voluntarily and after warning) was in itself just.

It was important for future events
It's also worth noting that the Ban only came after the rebel Noldor had been given several chances to return and talk things out, and after they slew untold number of the Teleri. Any parent will tell you that there's a time to be compassionate, and a time to be firm; genocide seems like one of the times to be firm.
The Valar let Middle-earth suffer during the War of the Jewels
You said "War of Wrath", but I'm pretty sure this is what you actually meant; the conflict between the Noldor and Morgoth that was the main subject of The Silmarillion2. The Valar had their reasons for allowing this conflict, which I elaborate in my answer here.
The Valar didn't help the Faithful of Númenor
This is simply untrue.
The Valar exacerbated the rebellion of Ar-Pharazôn
As Shamshiel pointed out in an answer to one of your questions, the lightning-warning from the Valar was only one in a series of warnings sent by the Valar to the unruly Númenóreans; they didn't decide to deal with the uppity mortals by chucking lightning at them3, they tried several lighter forms of dissuasion before going Old Testament on them.
And, of course, you have to give Sauron some credit for the PR move.
1 For clarity: this is referring to the War between the Valar and Melkor that took place before the awakening of Elves, which resulted in Melkor being chained and Utumno destroyed.
2 The War of Wrath was a different thing; the conflict between Morgoth and the Host of Valinor that ended the First Age
3 What do you think this is, Greek mythology?
