Well, I always (CT anyway) kept Engineering (Drives) as a seperate section (behind a bulkhead) from the rest of the ship (Main) so I'm contrary to Bhoins on that point.
Life support was a percentage of the bridge allotment, 1ton ls/100ton hull iirc, of which half was the recycler units (in 1/2ton permanent modules) and half was the supplier/filter units (again in 1/2ton modules but replaceable*). I usually placed them adjacent to the bridge or main common space in my deckplans (behind access panels).
* Recharged/cleaned by starports A-D but typically just a swapped unit, empty for full, at normal cost, or a small deposit if you want to carry extra, like for extended missions
A bridge hit takes out life support in this scheme which is part of why bridges are so critical and vulnerable no matter the size. Of course (and off topic here) im(C)tu a bridge hit is handled more like a computer hit in book 2.
I've never been a strong believer in the ability of a ship (especially a huge one) to rapidly decompress the entire hull before battle to avoid explosive decompression, and then magically repressurize the whole hull after regardless of damage. So ships don't routinely do it imtu, instead they just suit up prior to engagement and if the ship loses pressure it's only in a limited area and the crew are fine (barring a crew hit of course).
Oops missed the galley etc. question bit. Back in a bit with a link to my old CT take on the whole deal.
