I suggest reading this whole topic to see what my post replies to and then reading my lengthy post. I really do believe you will be able to show a significant profit by sticking to the basic fundamentals as described there.

Then I suggest purchasing ICMIZER and choosing the SNG COACH mode and practicing your specific game type (you will find 6-max hyper KO SNGs there under Pokerstars). You will find everything regarding push/fold there, provided you are willing to put in the time.
I have never used a HUD with anything else except for VPIP/PFR, number of hands and number of big blinds and am doing quite well. I could probably do much better by using a more complex HUD, but it honestly isn't that important at these stakes.
VPIP/PFR will tell you practically everything. Even after just 10 hands, you know who the losing players are and you know who the possible reg/losing nit is. The thing to remember about bad players is they always do something in excess, to the extreme.
If they are tight, they are ridiculously tight, if they are aggressive, they are often literally insane etc.
Basic villain types on these stakes:
40/10 loose please-let-me-see-a-flop passive player
40/30 loose insane aggro player
10/5 I've-found-a-way-to-finally-show-a-profit nit
All are quite transparent so the countermeasures are pretty obvious and simple. You really don't even need 3-betting frequencies or anything even more intricate because you can usually just take an educated guess and not be far off. Of course other stats would help you be a better player, but I haven't gotten used to using them yet as I'm focusing on other things that I think are more important.
Good luck
