The gaskets are O-rings. They are cheap at the parts house bout a buck each.. Usually come in a set of six.
To remove the plug-in electrical connector from the injector, you need to release a small wire clip or bail which captures a pair of tabs on the injector body. You might need to use a mirror to see the clip, and small screwdriver or a nail bent in a U-shape and held with a needle nose plier to spread the clip away from the locking tab.
The fuel line quick-disconnect fittings are also a pain to remove - you may need to use a fuel line disconnect tool (a specific sized disc with a slot) to slide over the fuel line and to push the spring fingers in order to disconnect the fitting. Most auto parts stores carry them
Release any pressure in the fuel injector rail at the Schraeder valve before you disconnect any fuel lines, and collect the fuel with in a jar or with rags, then remove them from your engine. The fuel rail comes out easily after you unscrew all the hold-down clamps. Don't force anything - use a bit of leverage to gently pry the rail off of any 'stuck' O-rings on an injector.
At a minimum, clean the rail after you remove it, as well as the ports in the cylinder head after your remove each injector. Use paint thinner, or fuel injector cleaner or similar on a paper towel.
To reinstall each injector, you can buy a specific O-ring lubricant to wipe on each O-ring (one on the cyl. head port and one on the top where the fuel rail attaches.) Or use clean petroleum jelly.
Double-check everything before you restart the car (especially for any leaks) and then crank over the car.
Piece of cake..huh? Big Jim
