I would bend the cylinder first, as the tab is just one right angle 
bend, and easier to do second. If I am understanding you correctly.
If you are going to be bending the tabs cold, you can drill first. But 
if you bend them hot, the hole may change shape, becoming oval, 
depending on where it is.
But sometimes you have to drill a hole first, undersize, do the hot 
work, and then go back and ream or punch it to size- because its easier 
to get it in a drill  press or an ironworker when it is flat, but the 
hole distorts with hot work. Then you go back and ream with a cordless 
drill to get an accurate size.
