First of all I would like to begin by congratulating you for making an effort towards Salah. Any step you take towards Allah, Allah takes an even bigger step towards you. May Allah reward you and keep you (and all of us) steadfast in this.
As brother Atif mentioned, yes you are supposed to recite it after the Fard (obligatory) prayers along with other Adhkar - all of which are optional but beneficial.
Regarding the issue of the language of recitation, it is obviously preferable to be recited in Arabic since that is the language Allah revealed it in (Quran 12:2). And unfortunately no translation of the Quran does justice to the actual depth of meaning of the Quran. If you are a native Arabic speaker or an expert in Arabic, you realize the words in the Quran are not that of mere mortals like us.
Having said that, you can certainly read the translation while you are still memorizing the verse, but my advise would be to read the transliteration instead (after having read the translation enough times to know what the verse means - which you most probably have already). Alternatively, you could listen to the audio on your phone every time after Salah and recite along - it will make it very easy for you to memorize the verse if you follow this approach.
And Allah Knows Best.
Once again, May Allah reward you, and remember us in your Dua.
