[Q] How to root Note 3 with tripping Knox topic

I have a new Note 3 with 4.3. I'd like to do the following things:

* update to 4.4.2 (is it better to stay with 4.3 if I care about the other things I'm going to enumerate here?)
* root it, I don't care about knox
* remove most of Samsung bloatware (I like the clock and the pen stuff and would like to keep them) - does titanium backup still work for this, what do I have to care about to not brick the phone?
* install adblock and afwall
* all that without the need for a samsung online account

Are there any step-by-step instructions for these things, especially for rooting?
