I used to try to remember how to write hiragana and katakana, but I find that after practicing writing them all, after a few days I would forget how to write the majority of them.
The only way around this is practice. You need to practice reading and writing kana at least 20 minutes a day.
Here is a website that has kana and no kanji. Go down to the links for Princess Kaguya and Momtaro. Copy the kana from the screen and write them down.
Either if you have memorized the shape of Hiragana manually or by using mnemonics provided by our guide, you will still need to practice a lot of reading to lock them up to your long term memory. But yes, it’s not easy to gather material to practice Hiragana. So we try to create a page

Next is a website that reads kana out loud and you can write them as you hear them.
Here is some material to help you practicing hiragana and katakana listening and writing.

Next is a website that sings Japanese songs and you can read the kana as you listen to the songs. Click on a song, click on the "Japanese page" link in the upper left corner. At the bottom of the page are two links to sound files. Click on the sound-file on the right side, an you can listen to the song while reading the kana on the page.
I also find long and short vowels hard to understand,
Japanese is a short-syllable polysyllabic language, where the syllables are spoken with a quick, staccato sound. About 800 years ago, the Chinese language was introduced to Japan. The Chinese language is just the opposite, using a much smaller number of syllables per sentence and syllables that are comparatively long. For example, the sentence for "good morning" in Chinese has only three syllables, whereas the Japanese sentence has nine syllables.
The sentence for "I don't want it" in Chinese has only two syllables, whereas the Japanese sentence has seven syllables.
When Japanese people first heard spoken Chinese, they quickly noticed the sounds of the two languages were quite different, including the use of long syllables in Chinese and short syllables in Japanese. The Japanese people developed a way of distinguishing long syllables in Chinese and short syllables in Japanese, which is why we have words like KOKO (a 'Japanese' word') and KOUKOU (a 'Chinese word'). The distinction is very important.
Do you write it as おはよ or おはよう or おはよー?
It is written おはよう. If you see おはよー, I would say it is a type of slang, and you should not use it.
ー should be used with katakana only.
Correct.
