I would try to memorise all hirigana first if you could. It will make pretty much every aspect of learning Japanese easier for you if you do. You can probably do it in less than a week. I learned katakana in 4 days. (The set used for loanwords.) I had learned hirigana already so long ago, that I have no idea how long it took me back then.
There are charts all over online for this. Also there is a Japanese Resource thread somewhere on the forum… I think it or Riya’s “What do I do now?” thread has some stuff to learn hirigana. Maybe even a game.
I learned the katakana really fast with a free trial of iknow (iknow.jp) app on my phone.
Feel free to ask any more questions! : D
