Generally i guess u should be tight in EP and loose in LP. But it pretty much all depends on the table. If the table is really aggro, dont steal obv. Just wait for a hand since you'll get action on it. Or if u try and steal do it from EP so they'll give u some respect (not sure if this works in low buyin tourneys though so do it at your own risk )
With AQ its all about where u are on the table when u get reraised. In LP i dont think i would ever NOT play for my stack with AQ when im the first one in...at least not HU late in tourneys. In EP i would probably let it go.
I havnt seen any of your hh's but usually my general advice is to stop stealing so much and let the tourney come to u. Capitalize on other players mistakes. Dont just raise with any two in LP against aggro players in the blinds..be smart/patient.
