First orbit of a :20 minute tourney, questions on preflop, flop, turn and river

Interesting spot, early in this tournament.

Preflop: 

1) I split between iso raising here, and checking behind. With unknown villains, and the player pool (they limp/call a wide range, including some stronger hands that default regs would raise) I leaned toward a check behind with hand that plays well multiway, and is unblocking Villain's continuing range. I would be more likely to iso raise here with QJs, and KJs, and ATs, for example, since these hands block continuing range. Your thoughts on facing limpers, and exploitative adjustments for these "limp/callers"

Flop:

2) I lean towards checking 100% here, as my hand has equity, but also can improve. If either bets I will check/raise, but since my hand doesn't need protection, and has equity, I decide to check. I would consider betting most of my two pairs, and sets here to protect equity, but I tend to check here with most of my range...as a default strategy. Your thoughts

3) Check/raise sizing: At this effective stack depth, I choose a 2.5x @ 48bb effective, but considered a 3x or even 3.5x after the fact. Will PIO, but what is your opinion on sizing here? Multiple sizings based on holding. Larger with two pairs, set, and vulnerable straights...a smaller sizing with more protected strong equity hands like my holding...and combo draws. Splitting the flush draws into large and small raises...or just one size fits all. I would check/call here with BC hands and hands that can improve to strong hands that have equity against bluffs, e.g., As5s and 6h5s...I think...I will model in PIO, although with the Villain betting into two opponents, might be slightly off.

4) Turn line: Once the flush comes in, I decide to switch to a BC line, since my hand does well against bluffs, but is vulnerable to a portion of Villain's hands that called my x/r (the flush draws). Also, I can call a bet, but am not excited to call a turn raise from villain if I bet.

5) River line: I choose a value/blocking bet...to set the price of my river, with a plan to likely check/fold to a shove. My hand appears too strong to check/call the river, as I allow all of Villain's worse hands that would call a bet to check behind, and if facing a large bet after checking, I could be in a difficult spot where I am calling off a large amount of my stack. My main reason for betting, and the sizing, is to target Villain's sets and two pairs, and some top pairs with draws, to get a call for value. And to simplify my decision, if Villain raises...I will likely bet/fold as I can't find a lot of villain's river range I beat.

6) To call or fold: I mean this is a tougher spot. I am in the top of my river range, so I should call this min raise, but really, what hands in Villain's river range do I beat? Many mid to low stakes players aren't capable of a sophisticated bluff here...and all of villain's value hands I beat check here (most of them, if not all of them).

Your thoughts?
