Two consecutive hands in the end of a tourney - opinions please

[Pug conDoin]

Greetings,

last night in one tourney I played till 15/777,
and then got kicked out just before final table.
That sucked and I would like to have a some opinions
about, is my analysis of "what-went-wrong" right.

I played two consecutive hands badly, and would like
to discuss, could that be avoided.

Here are the hands and below each hand is my analysis:

Hand 1:
$50+$5 Hold'em No Limit
Level XVII (4000/8000+ante 400)
Seat #6 is the button
Seat 1: UTG (28764 in chips)
Seat 2: 2.pos (379609 in chips)
Seat 3: 3.pos (118072 in chips)
Seat 4: 4.pos (98343 in chips)
Seat 5: 5.pos (136080 in chips)
Seat 6: (B) (110896 in chips)
Seat 7: (SB) (346304 in chips)
Seat 8: Pug (BB) (83994 in chips)

Action:
Dealt to Pug (BB) [7h 7s]
UTG: raises 20364 to 28364 and is all-in
2.pos: calls 28364
3.pos: folds
4.pos: folds
5.pos: folds
(B): folds
(SB): folds
Pug (BB): folds
*** FLOP *** [As 7d 3h]
*** TURN *** [As 7d 3h] [4h]
*** RIVER *** [As 7d 3h 4h] [Jd]
*** SHOW DOWN ***
UTG: shows [Kc 3c] (a pair of Threes)
2.pos: shows [5c 5s] (a pair of Fives)
2.pos collected 71928 from pot

I have 77 in a 8-handed table. I should have called
that raise with 20 364, because I already had put in
a BB and I only had to call with one-fourth of my stack.
I just were worried about the first caller, I was
not worried about the raiser, I reckoned he might have had
anything from UTG at that point. I believe it was the first
caller who's call made me fold my pair of sevens. And as
usual, the caller had even smaller pair and one more seven
came from the flop...well that was mistake no 1.

And right after that came the next hand...

Hand 2:
$50+$5 Hold'em No Limit
Level XVII (4000/8000+ante 400)
Seat #7 is the button
Seat 2: (BB) (422773 in chips)
Seat 3: UTG (117672 in chips)
Seat 4: 2.pos (97943 in chips)
Seat 5: 3.pos (135680 in chips)
Seat 6: 4.pos (110496 in chips)
Seat 7: (B) (341904 in chips)
Seat 8: Pug (SB) (75594 in chips)

Action:
*** HOLE CARDS ***
Dealt to Pug (SB) [As Ah]
UTG: folds
2.pos: folds
3.pos: folds
4.pos: folds
(B): raises 16000 to 24000
Pug (SB): raises 24000 to 48000
(BB): folds
(B): calls 24000
*** FLOP *** [Ac 8s Ks]
Pug (SB): checks
(B): checks
*** TURN *** [Ac 8s Ks] [3c]
Pug (SB): bets 27194 and is all-in
(B): calls 27194
*** RIVER *** [Ac 8s Ks 3c] [Tc]
*** SHOW DOWN ***
Pug (SB): shows [As Ah] (three of a kind, Aces)
(B): shows [9c 5c] (a flush, Ace high)
(B) collected 161188 from pot
xxx [observer] said, "lolol"
(Pug: I deserved that comment...)

And of course, out with bullets I went. I should
have immediately pushed in, when in turn. But I got greedy
and wanted the full value from my AA. I could have made
the 9c 5c to fold before flop. And at least shove the rest
on flop, when one more A came. I gave the infinite odds for
big stack to draw. And he surely did it. Altough my stack
I have left was only 27 194, so he would have called on the
flop anyways, I think.

The main lesson I learned from here (once again) that in the
end of a tourney You just have to play your strong hands fast,
and NOT slowplay them.

Any more advice? Is my reasoning on the track at all?
Is there some points what I did not take into concern?

On my opinion, I could avoided this simply by calling with
77 on the first hand, and after getting trips, no worries
with that hand.

And then, on the second, just raised immideately all-in,
when fased the raise from big stack.

Many thanks for any opinions and advice.

Sincerely,

Pug
