To place images, hit "F" draw a box, followed by, IIRC, Ctrl+D*. That should pop open a file explorer window. Surf to your file and hit "ok."
Text tool is "T" hit that, draw your text box and type away. There should be a floating command palette called, iirc, Character that will let you set stuff like leading, spacing, scaling and other options. You can either highlight the specific text in a box to change just a few characters, or hit your "V" tool, click the box, and make your changes which will be applied universally. Sometimes it's hidden in one of the floating boxes, just be sure to read all the tabs. If you don't see that window, check under the "Window" (again, iirc) menu at the top and select Character as well as Paragraph.
I know we've got at least two other INDD users around here, one of them should be along shortly.
Don't sweat the software too much, I picked the basics up in a couple of days. Quark sucks, viva la InDesign RevolucÃon!
*Cmd+D on the Mac, I think.
