Firstly, please post any future questions you may have about the language in the Language FAQ sticky in Learning Japanese(from which most of this reply will be coming from). Secondly, I would like to state some general rules about writing Kanji(for anyone not aware)
#1- Vertical strokes go from top to bottom
#2- Horizontal strokes are from left to right
#3- When 2 lines cross, the horizontal line
#4- When forming each of the elements, start from the top left most element and work your way down(of course there are exceptions to this)
Thirdly, I would like to discuss radicals. Radicals in the context of Kanji are other parts of the language that come together to create entirely new words. Kuma(熊), for example, is composed of ム and ヒ surrounding 月 with one upward dash and 3 downward dashes along the bottom. There is a proper stroke order for all Kanji and in time you will learn them all, but as long as you keep those rules in minds, you'll be pick apart any new Kanji you may come across and at the very least have an idea as to how it can be approached.
A bit of cultural perspective: many Japanese often lose the ability to remember the stroke order to a lot of Kanji as their use for physically writing it decreases and they become more reliant on other means, such as E-mails and cell phones, and if it's to complex/unnecessary for them to write they often just write it in Hiragana, which sometimes becomes an accepted thing to do among the general population(such is the case with the 2 verbs for existance,有(あ)る & 居(い)る)
To end it, something that might be of aid to you in the future

Although it is on a website that helps English speakers learn Chinese, this is one of the best sites I have come across to learn and practice Chinese characters in general. For the most part, the ones used in Japan aren't that different than one's used in Taiwan and the mainland.
Anyway, here's a link that might help you.
