recent home inspection questions

soon to be purchasing new home (10 yrs old).
had home inspector (licensed P.E, etc) take a gander at it.
he came up with the following that i'd like opinions from the "pro's" on.
(a).the chimney chase shows rusting and prior caulking (some old water stains were evident on the inside of the attic underneath it).
he states it's okay at the moment BUT said it should be addressed (ie. replaced) before winter of 2006.
what's an "average" ball park figure to do a job like that ? (i'm in the northeast). need an estimate to discuss with the seller.
(b).CCA lumber was used in the construction of the wooden deck. should i be worried ? (the inspector said "no", but wanted to point out the hazards of arsenic possibly leaching out into the soil).
should i even bother with mitigation steps? (ie. perhaps paint over the CCA lumber and remove / exchange the soil around the pilings?)
(c).nuts on a beam sill plate were missing washers which the sill plate tie down bolts should've been inserted thru.
he stated this caused the nuts to be gouged into the sill plate - but also said it's "structurally stable", but not structurally "sound" (ie. it's not going anywhere unless a major tornado or level 3 hurricane hits it).
should i be worried about these missing washers ?
thanks in advance for any opinions/feedback

A PE in what? Every PE I know is working in their field and making a lot more than a home infector unless he is working for himself.
(a) Hard to see your problem from here. Contact a licensed contractor in your area.
(b) Without knowing the exact situation it is next to impossible to guess at a response.
Good luck with your purchase.

A. No idea. B. Don't chew on the deck. C. Replace the missing washers.
You could do what most people do and tell the seller you want $850 back at closing to fix those things. Then go buy a new TV.
