how good is your limit hold'em - book title

Hi,
First like to say this is a great site.
Though still something of a fledgling I'm becoming dangerously close to obsessed with the game. The usual tell tale signs are there - "I'm calling the solicitor, now" and, "I'm off to my Mums, again", are among the not unrepresentative comments of the current Mrs B.
Still life/poker goes on.
Which in a round about way ( I promise not to go on so much in future posts ) brings me to the crux.
I've seen a number of comments on here about the above book.
It is thought provoking and makes you consider situations rather than just trying to absorb masses of info that you are sometimes confronted with. However ..., I'm struggling with one or two issues that perhaps someone in my new community might be able to enlighten me/support me on.

Hand 1 Bizarre bunch
I know there is a thread on this but it starts past where I am struggling with it. So starting from the top.
Hero is BB (A 10 clubs.)
CO (Jonny - competent, solid bit timid)
UTG Bizarre (makes odd plays, has strange mix of passive/agressive)

Bizarre raises
All folded to Jonny who calls.
Book - Q. What do you do ?
I'd probably fold but to follow this through a bit further say I call.
Flop
10h,8h,6d
Somewhat dubiously Hero bets.
Bizarre raises, Jonny calls two bets cold.
This is where it would too hot too handle and I'd muck.
However Hero calls !
As stated perhaps someone can explain.
the example is a $20-$40 game so decent starting standards must surely apply. So my read would be

Bizarre raises - he has high pair, maybe AK, AQ at worst.
Jonny calls - with that he should have something similar.
Hero calling is dubious.
post flop
Bizarre raises Heros bet (first klaxon), Jonny calls 2 bets cold - I'm getting deafened.
At this stage the notes to the answers in the book state that hero has top pair, top kicker. Does he ? The raising and calling of the others suggest different, at least one of them may have a higher pocket pair.
Maybe I'm just more fledgling that I care to admit (to myself), but then any education would be welcome.
