What I would recommend is reading and making sure to watch anime with Japanese subtitles, aside from that there's probably not much for you to do right now. I suppose you could keep Tae Kim's guide as a simple grammar guide to casually skim through when you encounter a grammar point you don't understand?
Regarding reading I'd say you can start whenever you want. Since you have fuckall vocabulary it'll basically just be you going through 90% of the words in a paragraph with yomichan, every single paragraph, but even then it'll expose you to those words as well as let you get used to the kana better. I had the same experience with Yotsubato back when I had started it knowing just 500 words and having to blow over an hour for every single chapter, and I'd say it was worth it. You should try some of those readers, and also think up of a few pieces of content you'd like to read, ideally something where you can easily use your digital dictionary. I recommend you try reading https://www3.nhk.or.jp/news/easy/ frequently, since it uses both a limited vocabulary and simple grammar it'll help you hammer in both of them. You could also try the VNs from Yuzusoft and also the Steam version of Little Busters. The former has a system that allows two languages to be shown at the same time, so as a beginner you can enable both Japanese and English and compare between the two for lower-level reading, and the latter allows you to switch between Japanese and English instantaneously with a right click. I played Little Busters this way about 6 months after starting to learn, reading Japanese and only switching over to English when I understand the sentence but don't know a single word, or don't understand at all and want to be able to grasp how it works(as well as of course the story). The good thing about this is that you're able to engage with the language in a way that isn't intense or stressful.
