Have you tried Anki? Anki is a free srs program which is great for studying languages. I learned a lot of kanji through a combination of Anki and reading a lot of manga and novels in Japanese. You can also try James Heisig's Remembering the Kanji method, which works very well.

I have enjoyed using www.jisho.org ; じしょ is Dictionary in 日本語！I hope this helps you!

Kanji Pict o Graphix (Over 1,000 Japanese Kanji and Kana Mnemonics) by Michael Rowley is a very helpful resource and easy to use. There is also an app as well as other books by Michael Rowley. Also, there is Chineasy, but that is more for learning Chinese.
