One step at a time bro don't burn yourself out!
The Quran was revealed in arabic because it's the best language to reveal the Quran in. To me it is much easier to memorise the arabic as it's flow is perfect, I would advise memorising it and then learning the meaning. But you can do whatever you feel is most comfortable.
Below is a video of "Al Fatiha" or "The Opening". The first chapter of the Quran, it is recited in every prayer. You might find it a little hard to pronounce the transliteration as I'm sure you are not used to reading arabic words transliterated in alphabet. If you want you can read and imitate at the same time so you might get an idea of the correct pronunciation.
There's a
brother on youtube who is a convert and I remember when he first started he also had some issue with pronouncing the arabic. I think it differs with people, I've seen some able to pronounce it easily and some needing a bit more time.
Rest assured, we are judged by our intentions before our actions. Even if you make a mistake, God knows what is in your heart.
P.S The first line recited "I seek refuge with Allah from satan, the outcast" is a small prayer said before reciting any sura/chapter.
