translation please?

I heard learning phrases and translating them is the best way to learn hindi. Does anyone think they can translate this introductory passage for another italki group (called " अतुल्य भारत की सरल हिन्दी सीखें ") that showed no translation and everyone wrote in hindi so I was a bit intimidated to ask. I somewhat understand but there is new vocabulary in there that I don't understand. Thanks.

"Agar aap kee atulya Bharat kee Hindi Bhasha sikhne mein ruchi hai ya phir aap ko Bollywod kee Philme Shahrukh, ya sangeet, bhangra dance pasand hai ya Bharat kee sanskriti, Yog-Dhyan, Rahan Sahan, Khan pan, ya kuch bhi jankari prapt karna chahte hain to mujh se sampark kar sakte hain. Hindi sikhne walon ki madad karna hi es samoh ka lakshya hai."

When does one use only "pas" without the "ne" in a sentence. for example i saw this somewhere.. "Dommage qu'elle chante pas plus dans ce vidéo. Is it just conversational? or there an actual time that one must use it?

What's the difference in sound between the futur(simple) and conditional tense in "je" form? for example : j'aimerai and j'aimerais is there a difference in sound or does it just depend on context?

What's the difference between gray and grey?
