    I have a couple of boards that have a "plane" on one side. Am I to assume it is always for ground? Can I put anything I want there or might that cause interference? I would prefer to put Vcc there actually for my little use case. Sound ok?

    Boards have a ground plane because it helps to reduce RF emissions, and because practically everything on a circuit board will need at least one connection to ground (IC's that is.) You're much better off to keep using that side for a ground, and running Vcc elsewhere. Use bypass capacitors at each IC to keep noise under control.

    What kind of board is it? Is it a solderless breadboard? Or is it a board for etching?

    It is the kind with plated holes, spaced on one side and separated by one potential solder blob from a full plane on the back side. Ground it is. Bypass caps should be somewhere around what values? Thanks.

    It's typical to use 0.1uF tantalum or ceramic capacitors to bypass the Vcc (and Vdd, if not ground) pins. Consult your IC's datasheets for specific recommendations.

    You should have convenient power rails on that. Do you have a link to it and how much did it cost? I'm always looking for cheaper ones.
