Okay, so up until a month or so ago I've been a complete beginner when it comes to formally (I mean that in the loosest sense possible) studying the Japanese language. My experience with the language before I began to actively attempt to learn it basically amounts to several years of enjoying subtitled anime (I've watched DBZ, Naruto, Bleach, Samurai Champloo, Full Metal Alchemist Code Geass and other popular animes pretty extensively in my day) a decent amount of translated manga (if that means much of anything) and television / music scattered here and there. That's basically the extent, or limit, of my knowledge of the language and culture, just to let you know.
In terms of what I've been actually doing to study, I've been using Rosetta Stone level one and two weeks ago started using RTK 1, along with RTKana (Rosetta teaches Hiragana in a very scant and spaced out manner and I've yet to see a lesson in Katakana yet. There are Katakana characters if one chooses to read in hiragana/katakana form), as my Kanji and Kana learning resources.
As far as my progress goes, I'm about halfway through level one of Rossetta, 249 Kanji through RTK and have pretty much familiarized myself with hiragana to the point that recognizing and writing the characters doesn't require too much effort, with the exception of diacritics, digraphs and diacritic / digraph combos of which I'm still in the process of internalizing fully. I have yet to dip more than a toe into Katakana and am fully aware that Rosetta Stone has it's limits when it comes to explaining grammar, sentence structure, and the explicit meaning of certain vocabulary words which is why I'm here in the first place.
For the TL;DR version: What exactly do you guys recommend I do as a beginner in order to shore up some of the gaps I have between Rosetta Stone, RTK 1 and RTKana right now? I've lurked this site for a couple of days now and can't seem to find a strategy that works with what I've been doing so far.

I started RTK in February, but I made sure to learn the kana beforehand.
