1) You have a huge leak in between your VPIP/PFR gab - most likely losing a lot money by just cold-calling. You should start to raise more hands rather than just limp or Call vs raises.
2) Calling too many 3bets - HUGE LEAK - prediction is that you losing most of the money here.
3) You could be a bit more aggression on early streets, right now the aggression for you on all the streets is kind of the same. But which should be that on flop you have the most aggression and then on turn less and on river the smallest one.
4) Seems like you ain't doing very good with CBs, success is kind of low, especially if your CB is so small it should be a bit bigger.
5) You don't play much according the position, you play practically from any position almost the same. You should widen up your range late position which also includes that you should steal more.
6) Blind defense - most likely you defending too much the blinds as we see from the SB.
I use the HUD often, only the standard stats, but do you think it would be more beneficial to my learning experience if i were to disable HM and just use it to review afterwords?
Nah, if you have the HUD then use it.
Especially if you bought HM for yourself. 
Playing without a HUD should also improve my basic ABC game too, making more reads opposed to just using stats?
Answer above.
No need to disable them.
Player has X hands?
Some are using it, depends really what you like more.
I use from hand sample 1. ♦
I've also barely posted any hands for review, which is stupid of me not to use Veriz brain power. I've just posted about 25 hands from the 35k, seems you've found a huge leak from me already. Over playing my TopPairs/OverPairs, also playing for stacks too often.
Well, a lot of pokerstrategy members don't see the huge profit what comes from posting/discussing hands.
They are just too lazy to do that.
Also, would you say that reading everyones Hand Review Threads is also worth it, or just my own?
Well, I guess there are too many in NL10 for to read all. ♦ Just post your own and then you can easily keep track on them and will even fix your own leaks. 
I'm thinking of deleting my entire database of cash too, to start a fresh, would you advise this is a good idea or bad?
Yeah, I do that time to time as well. Especially if I have very old information on some opponents and a lot of that.
