I'm keen to get the most out of my chest exercises but I'm struck with the misfortune of not knowing the best sets to do.
What are your aims here, strength, size, endurance.?
db presses are good, and help build up the accesssory muscles in your shoulders and back, and can at times give you a good lower back and ab workout, esp. when one arms goes up and the other does not, forcing you to compensate and focus on the lagging arm.
I do flat bench first, stepping it up each set getting heavier and heavier, until I get to my 2-3 rep max, once a month I go for max x 1 rep.
Then i do either incline, or decline db presses or pec dec, again ramping up to a 3-5 rep set,
I also find weighted tricep dips, wg pullups, and front raises help to get a stronger bench.
