She is right, we can omit ra when it's possible and doesn't change the meaning. it is done naturally by native speakers cause they know how these sentences change when we use ra and when we don't(in term of meaning). therefor I suggest you to keep using ra even in second sentence just after all direct objects till you become fluent and you can distinguish how the meaning of the sentence changes if we omit ra, sometimes it can make the sentence meaningless sometimes.

Is it right?

at first I correct what you wrote then I tell you how to write this sentence just like a native speaker would write:

دوستمہ به زودی روزِ تولاد دارد(روز تولدستم است)(به زودی روز تولد دوستم فرا می رسد). بعد از ان (آن) تعطیالت (تعطیلات) نیکالسِ(نیکلاس) مقدس(سنت نیکلاس) است از این رو  من برای (به) او دو هدیه می دهم(خواهم داد)    م

this form is still too formal but it sounds better:

به زودی روز تولد دوستم فرا می رسد. پس از آن هم تعطیلات سنت نیکلاس خواهد بود. از این رو به او دو هدیه خواهم داد. 

this one would be less formal and the way I would write such a thing!

 .چند روز دیگه تولد دوستمه (تولد دوستم است). بعدش هم (بعد از اون"آن" هم)تعطیلات سنت نیکلاسه(سنت نیکلاس می رسد). برای همین می خوام بهش (به او) دو تا هدیه بدم.

 no need to translate saint Nikolas although your translation is not wrong

hope it helps you!

 

o0ops! :O who are you talking with?! seems you should change your partner!? knowing slang should be the last stage of learning a language for my money

peyvastan(ya ozv shodan) be (dar) baashgaah(ya cloop) e bafandegi behtarin tasmim e zendegim bood (ya behtarin tasmimi bood ke taa konoon gereftam)

to study believes and stories(narratives) of ancient ethnics(communities). you have to change your font in Persian we don't use such strange font (that's more likely Arabic)

actually you should know the root of the words (adjectives) you wanna use with that suffix, غیر is an Arabic suffix and you can not use it for Persian adjectives so غیر+ adjectives with Persian roots =non-existed and incorrect! غیر+adjectives with Arabic roots= correct (ex:refer to given answers) as our friends mentioned.

we have to use را just after direct objects in Persian. you should learn which verbs in Persian require direct object.
