For example if i say something like,"あなたはやさしい人です”。

Versus if I say,"あなたはやさしい人".

Is the second sentence (stated above) grammatically correct or does there
"need" to be a particle at the end of my sentence?

I appreciate all the help I can get from you wonderful people.

Please give me your knowledge and help me better educate my self.

Does using the characters です at the end of a sentence make almost everything(depending on the sentence) sound polite?
There are actually three sentences worth discussing

> **(1)** あなたはやさしい人です
>
> **(2)** あなたはやさしい人だ
>
> **(3)** あなたはやさしい人

For each sentence, we should consider three dimensions: **grammaticality** ,
**softness** , and **politeness**.

(1) is **soft** (doesn't sound too direct), **polite** (shows respect for
addressee).  
(2) is **rough** (sounds like a point's trying to be made), **not polite**
(doesn't show respect for addressee).  
(3) is **soft** (doesn't sound too direct), **not polite** (doesn't show
respect for addressee).

_All three_ are **grammatical**.

(Note: "Not polite" doesn't necessarily mean "rude". There is no need to use
the polite form with your friends, close family, or people much younger than
you, for example -- in these cases the polite form would be overly distant or
odd.)

(Note 2: It's probably worth pointing out that the presence of あなた makes all
of these sentences sound a little jarring.)

I believe Darius hit all the points on how it differs in spoken Japanese.

I'd like to add that **tone** and **context** also play a huge role when it
comes to spoken Japanese, or any other spoken language for that matter.

Generally speaking, `です` at the end of sentence has a high likelihood of
signifying politeness, but it also depends on context and tone (which I will
only discuss context since I can't show you tone). For example, you see your
friend picking up trash for a stranger who dropped it intentionally, and you
reply:

`あなたはやさしい人（です）。`

It could imply a number of things, such as:

  1. statement: "You are a nice person." (especially if you don't know this person very well)
  2. re-affirmation: "You are indeed a nice person"
  3. surprise, "Wow, you sure are nice."

could also be any combination of the inferred meanings depending on the
situation. If sarcasm was intended though, `です` at the end would actually make
it more informal and in some ways "rude." Plus, if you use `あなた` altogether,
it could sound more impolite than polite.
