If you have hardwired alarms, it's best to have the same model for all, otherwise you can get unexplained alarms going off.
Vacuum out your alarms every 6 months (or more often if you have a lot of dust or spiders). Debris building up inside them can cause them to fail or alarms to go off inexplicably. If you're remodeling or doing something that will create a lot of dust, remove the alarm temporarily.
Ionization alarms are the ones that cause a lot of nuisance alarms (the ionization only alarms are the ones that tend to be dirt-cheap). Some have started recommending photoelectric only (or mostly photoelectric only and maybe one combined photoelectric/ionization). Keep ionization alarms out of areas near the kitchen and bathrooms (moisture from bathrooms can set the alarm off).
Buying CO monitors separate from fire alarms means that if one alarm mechanism goes bad, you don't have to replace the whole thing. Unfortunately, some states now require them to be combined - but if you own your own house, you can do what you want (unless you give an inspector some reason to require you meet the regulation, like remodeling).

Yes, but follow installation instructions about avoiding "dead air" spaces.
"On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is not possible, install the Smoke Alarm at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical "dead air" spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms may be required depending on the length, angle, etc. of the ceiling's slope. Refer to NFPA 72 for details on requirements for sloped or peaked ceilings."
Well that was 2014, and those 10 year battery ones never last
First alert and maybe other will replace for free if they fail early
