An unlucky outcome but still a good move

What do you think of this line?

Limped pot, I'm on the BTN and limp along with Q5s (live 1/2, $1050 stack size; have everyone at the table [easily] covered).

Flop comes Q Q 3 rainbow.  Checks around to me, and I lead for $5 into a 6x$2=$12 pot.  I get a call from the most readable guy there; definition of calling station, who will call HUGE bets down to the river with any and all pairs, and totally passive.

Turn is a 5, and I'm convinced that he has a Q and will call any bet.  He checks to me and I'm not yet thinking out of the box; I bet $25 into the now $24 pot.  He calls.

River is a 7 and he leads for $30.  He has $300 behind.

I shove the $300 effective into the $100 pot - he INSTANTLY calls and shows Q7 for the rivered better boat.

I just think there's so many hands that he's calling a shove here, without the nuts.  I think this is profitable, though unlucky that he hit his [second time on the night against me] 6%.

What do you think of the overbet for value?  No matter, in this case it would have been the same outcome (i.e. if I go through the more standard raise / re-raise / shove process), but he's clearly check / calling his weak Q as a bluff catcher, and will call off tons of $$$ with the non-nuts bluff catch.  Same could be said if the river double paired the board with a 3.  I think that in these situations, you need to extract max. pain against the loose / passives who are happily calling you down "just to see."

The hand earlier in the night, I flopped TPTK where I raised to $15 PF and he called his T6s (WTF?).  Flop is J T x and I got 3 streets of value on him when he hit his 6 on the river for 2 pair (he check / called my $45 river bet, which I debated checking through).

Sigh...  That hand above was the difference of a $1200 winner (which would have been single session tops in my short live poker career), vs. $500 winner on the night...  Oh well.
