Screw Something Into Stud And Nails Pushed Out?

Goal:

I'd similar to install a wall mounted shelf arrangement in my bedroom. It'southward composed of vertical wood rails that screw into the wall, and then shelves and cabinets are hung off of the rails.

Background information and reference pictures:

I've already installed a section of the organisation successfully in my kitchen, which as far equally I can tell is drywall- was fairly straightforward to install and I used the plastic drywall anchors that flip up to grip the wall (brand name 'wallclaw'.)

Motion-picture show of installation in kitchen drywall shown here:

I am pretty sure that the bedroom where I want to install the remaining shelving is plaster, not drywall. I've read various advice on how to test this, but I'm still not sure. (I can insert a thumbtack in the wall, simply it takes a little endeavor. Can't really tell from tapping the wall and listening. An cheap electronic studfinder has inconsistent results, a magnetic one merely sticks in a few places.)

I had previously put a hole in a different wall in the target room, and plant forest with a horizontal grain that is 'bouncy'- I'one thousand guessing this is the slats plaster is adhered to and information technology means the entire room is plaster.

Picture show of hole in a different wall in the target room:

I purchased a higher end studfinder (Zircon Metalliscanner m40) and in broad scan manner I seem to take plant studs xvi" apart. When I scan vertically in pinpoint mode it seems to find a vertical row of nails- then I'g guessing this is where horizontal slats are nailed to the studs.

Question summary:

• Given the evidence above, is the wall plaster, and not drywall?
• If it is plaster and I don't want to go into studs, what anchors should I apply- I'd like to put books and some heavy objects on the shelves and the weight is distributed between four seventy" vertical runway, 32 inches office, with iv screws in each rail (resulting in 3 "bays" of shelves in between the rails)
• If it is indeed plaster and I want to spiral into the studs, is the best way to drill a pilot hole then merely go all the way through with a wood screw?
• Am I correct that this ways in that location are nails or screws throughout the entire meridian of the stud? If then, what is the all-time way to avoid hitting these with the screws when I attempt to screw the rails into the wall?
• Annihilation else I demand to worry about, similar exposed wires behind the wall? (Plumbing is very unlikely given the room)
• What'due south the best method to ensure the rails are perfectly parallel to each other and ninety degrees straight up and down?
