My personal advice would be to start with the kanji order that Japanese children learn them in.

If you start somewhere random or by following a random Japanese textbook, you`ll have a bunch of kanji that you know but that are scattered... You may be able to read something quite advanced, but be lost on simple things.

When it comes to learning in the Japanese order there will be no shortage of materials just at or just above (enough to be challenging but not discouraging) your level as you advance. There are children`s newspapers, learning materials aimed at adults with learning disabilities, novels, etc - all following the Japanese curriculum order.
