You need a subject and a verb. This is true whether the clause is dependent -
"The dog jumped onto the sofa"
or independent -
"The dog who jumped onto the sofa"

No, "were" is not a relative clause. "Were" is a past tense form of the verb "to be" and can be used to form the past tense of a sentence or express a conditional statement, but it is not used to introduce a relative clause.
A dependent clause needs to be combined with an independent clause to form a complete sentence. It lacks a subject and verb that can stand alone to express a complete thought.
The subject of the noun clause "what you need" is you.
The clause 'What you need most' is a relative clause with the word 'what' functioning as a relative pronoun. The clause 'relates' to the antecedent for the pronoun 'what'. Example:Time is what you need most. (The noun time is the antecedent and the clause is functioning as the object of the sentence)What you need most is a good kick in the pants. (The noun kick is the antecedent and the clause is functioning as the subject of the sentence)

No, a dependent clause does not express a complete thought on its own. It relies on an independent clause to form a complete sentence.
A dependent clause is called a subordinate clause because it cannot stand alone as a complete sentence and relies on an independent clause to form a complete thought. The subordinate clause adds extra information to the independent clause, but cannot function independently.

Yes
Only an independent clause can stand independently. A dependent clause is dependent on an independent clause.
