Yeah, I'd say it's worth it. Most things written in Japanese aren't strictly only in hiragana and katakana, unless it's meant to be accessible for kids. You'll be able to read recipes, news articles, magazines, and more if you learn kanji. I also think it's vital if you're planning on moving to Japan (which i see a lot of learners wanting to do). I usually learn with kanji stroke order books, and they have ones for each level. They're available at stores like Kinokuniya, Barnes and Noble (in the language section), or on Amazon (heres a beginners kanji book)
I found the 'Learn Japanese Kanji' books to be useful for writing practice. (www.amazon.co.uk/Learning-Japanese-Kanji-Practice-Book/dp/0804844933). You'll likely know all of the Kanji anyway, but sitting down and just practicing the stroke order really helped me improve both my handwriting and get a good feel for the natural stroke order.
