Use the Relay class - it works like this:

If it is a limit switch (a simple mechanical closure), connect the common and normally open (or closed) contacts on the limit switch to the ground and signal connections of a digital I/O port. Then use the DigitalInput class to read the state.

Yes - this connection is correct. Use the Solenoid or DoubleSolenoid class to control the solenoids.

We use this one: http://www.maxbotix.com/documents/MB1020_Datasheet.pdf

The datasheets for each are on the maxbotix web site. For the MB1020 the analog number is VCC/512 per inch.

Good Luck!
