A little more detail:

The PSII launch controller uses six C-cells for power vs. four AA-cells in the E-controller. Both have 30 foot leads (which you need for E and up). If you’re planning to use the Estes Es and Fs, then what you are getting will be just fine, as they use the same igniters/starters as smaller Estes motors do. As kevinj suggested, if you are planning on using composite motors you may or may not want to/need to upgrade.

On the pads - Kevin pretty well summed it up. On flat ground and with moderate winds, what your’re getting will do.

Many people try to “improve” the PSII rockets with epoxy and fiberglass and such. They work JUST FINE when built as directed with the adhesives directed. Now if you’re looking to put a G80 in one of them then I’d think a little bit about some moderate strengthening.

If you’ve built recent Estes kits you’ll be in familiar territory with these three models save for the sizes of some of the parts.
