I would do kana word -> defintion in english so you don't get lazy and rely on romaji.
If you have a iPhone or Android, the app Kana Card Free has the basic Hiragana, katakana, and some Kanji. It only has the basic 46, not all the variations. Good for study on the go.
Making your own flashcards are good, I have a set of basic vocab words in both kanji and hiragana on one side, the back side has up top, the litral meaning of the kanji, then in middle, the word in romaji, under that is english translation., with sometimes a literal translation included.
Example:
おねがいします (front) 乾杯 (front)
かんぱい
Back
Wish dry glass
O-negaishimasu Kanpai
Please Cheers!
humble wish
As you study each lesson, on the season 1, write down the vocab words in kana form with english translation
This will help you learn writing kana, and also how they all work together. If you don't know the kana by memory yet, use the lesson notes Jpod provides if you have subscribed. If you can't swing the full premium price, the basic has a lot of tools available for you to use that would help.
Walmart has the set of 50 index cards on a spiral layout that you can use for portable flashcards since I haven't found any index cards or cards with a hole in the side for use as stereotypical Japanese flashcards you see in anime/manga.
I. myself, work better in learning by writing everything down then highlighting the important parts or whatever. Some people, though, do better just highlighting printed papers, like the provided lesson notes.
Try several different things, and see what works for you.
