Hi guys,
I'm designing my first PCB for a big school project and I had a few novice questions. Thanks in advance for the help.
I'm creating a simple breakout board for an XBEE series 1 and an Adafruit bno055 IMU. In the case of the bno055, it's really a breakout board for the breakout board. I want to be able to plug in the Xbee and the Bno055 breakout into my board, and have traces which lead to a six-pin header at the end of the board. That six-pin header will go to six pins on my microcomputer - SDA and SCL (I2C for bno055), RX and TX (UART for Xbee), and Vcc and GND (both of which will be supplied by the microcomputer).
I've been following Sparkfun's Eagle guides and so far, I have made what I believe to be the correct schematic.

I have two questions:
- Are these individual VCCs and GNDs I have all automatically connected to one another?
- For the Xbee, what I really want is the header holes for an Xbee series 1. Is placing the Xbee component in my schematic really creating header holes of the proper dimension in my PCB?
- The bno055 will be a bit more tricky. There is no eagle file for the PCB on the adafruit website. They do, however, have the dimensions for it. I'll have to align the header holes just so, so my bno055 breakout board will fit onto my own PCB. Do I dimension it at the schematic level, or the board layout once I move onto that?
