Hey,
I'm gonna mention a couple of things and perhaps give you a few recommendations, and then I'll try to answer some of your questions.
1) It's very, very difficult to get started speaking Chinese (I found it to be like this at least). If you want to start speaking very early, then go for it. I'm a proponent of people doing what they want to do, but I personally didn't do that. I found it very hard to speak, and even harder to understand what people were saying to me (which is why I worked on comprehension first). I would personally recommend working on a base of understanding before you start speaking, but as I said - each to their own.
As for easy reading content, here is what I did - I started learning characters almost from day 1. And, to be able to read, you DO need to learn the characters - nothing is actually written in Pinyin. In China, Pinyin is merely system for showing people (mainly foreigners) how to pronounce the characters (and you will actually find that some people in Taiwan can't read Pinyin. This is becoming less common and most young people can read Pinyin, but I do have a Taiwanese friend who can't read Pinyin. She uses a system that they teach in Taiwan called BoPoMoFo. There is also a system in Taiwan called Zhuyin, but these are only common in Taiwan). I would recommend bulk learning the first few because they come up everywhere in every type of text. "The first few" is very ambiguous. Some people I know bulk learned 100, some 200, some 1000, some 2000, some more. It's up to you, I'd recommend AT LEAST 500. After that, I'd probably recommend learning the characters from what you read, and not learning them from lists. Incipiently, learning characters seems impossible. It's not and it DOES get easier. Stick at it.
