I never really was a star gazer till now, up graded my scope and need some help knowing what eyepieces or barrow lens are good for it. I want to see further see the beautiful deepness that space has for me

Your telescope is a 6" f/5 Newtonian, like my own, and with a 750mm focal-length....

It's the focal-length that will help you determine the powers you're able to achieve, with an eyepiece, or an eyepiece combined with a barlow.  You may want a short barlow for your Newtonian, one that doesn't stick up out of the focusser too high...

A 2x-barlow, like that one, will effectively double the focal-length, and to 1500mm.  You might want to consider a 3x even...

That one would triple the focal-length of the telescope, and to 2250mm.  For example, I like to combine a 12mm 60° eyepiece with a 3x...

The 12mm inserted into the 3x-barlow becomes a simulated 4mm, and for a power of 188x.  You can see the Moon and the planets up close with that combination; and the Trapezium within Orion this winter, a beautiful and tight cluster of stars.  Higher powers do require that the collimation of the telescope be spot-on, almost perfect, and for sharp, pleasing views.  We are at the mercy of the atmosphere however, and that will play its part, too, in your success.

There are quite a few amateurs who don't use barlows at all in reaching the higher powers.  But the high-power eyepieces they choose to compensate, where they can omit a barlow, are more expensive.

Many deep-sky objects are best seen at low-to-medium powers, and with no need for a barlow.  For your lowest power, and in helping the finder-scope or red-dot finder hunt for and then find objects to observe, a 32mm Plossl will serve...

I have that one, and it's worth the wait.  Many astronomical items, during this time, are in short supply.

Do you have an idea as to how much you want to spend on eyepieces and accessories?  Plossls are the minimum in performance eyepieces, and are a great value...

...but when you choose shorter than 9mm, the eye-relief is tight, and where you have to almost touch the eye to the eye-lens of the eyepiece to see the full field-of-view.  Also, the eye-lenses are tiny.  This is my Vixen 6mm Plossl...

The views are great, if you can get close enough to it.

Next up from the Plossls are these...

They offer greater eye-relief, somewhat wider fields-of-view, and larger eye-lenses through which to observe.  Arguably, the best focal-lengths among those are the 8mm and 12mm.

I do have the same tube as you minus your spotting scope, i have a low power 5x barrow lens that i use with my 21 mm plossl eyepiece it has wide view. Great for the moon i love it and i use it with a celestron 8-24 m,m zoom lens as well. But i havent yet masted seeing the milky way or star clusters with colors, this is my goal. On the hand i have a very intresting  video i captured on my phone when i was looking at Saturn its two objects like  a reddish  brown in color coming out from the bottom leaving and around 5 hrs later one came back my girlfriend was mad at me for staying up all n ight but i showed it to her and well now shes into it as well now.
