Newbie: Can't figure out basic starting points; speed and pan/zoom

I am a first time newbie having trouble getting past what seem to be basic steps.  I've watched tutuorials and read help articles.  But I can't seem to move forward.

I've created a project and imported a series of time-lapse photos.  I can play the video in the editing window but two things are vexing me.

First, Pan and Zoom are turned on in a very distracting and annoying way.  If I go to the Effects menu and turn off the switch, it seems to have no effect and the annoying pan/zoom continues.  How do I turn it off for the whole clip?

Simlarly, I want to speed up the time-lapse. Selecting the Speed menu shows the Range handles. But they are greyed out and I can't drag them or change the speed. How do I get them to turn blue so I can edit?

Is it because each photo is treated as a clip? If so, it's not at all clear how to assemble them into one clip for editing.
