For that to happen you would have to assume at 800 RPM the Civics oil pump couldn't supply enough oil for the demands of high load at low RPM. And the potential for this type of damage increases the longer you operate the engine in this situation. If you are at WOT under these conditions then yes, you will have some issues if it's a habit. I was referring to the pinging and knocking people associate with lugging.
Under moderate loads around town, lower RPM's are fine. I do it everyday on the flat roads around town, anywhere up to 75% load. 60,000 miles and counting in the last 2 years with no issues. Generally I downshift when I can no longer gain any speed in a certain gear. Under the OP's situation there is no way a Civic is maintaining or gaining speed at around 1000 RPM's up a hill, so obviously it would be wise to downshift. I don't think I ever truly "lug" the engine.
I don't know what you mean about the clutch, where did 2200 RPMs come from?
