Which way should Q2 be facing? If you take a close look at the photo, the round end is facing us (flat end facing away). So I have 3V connected to the emitter. I wasn't sure witch way to face it because the schematic drawing of the 2n3906 is different than that in the datasheet I have for it.
What do you mean by the schematic of the transistor being different? The 2N3906 looks like any other PNP transistor on a schematic. There is no relation between a schematic and the physical layout of the part, you have to refer to the datasheet to tell which physical pin is which.
I don't know, the schematic for the circuit draws the 2n3906 differently than this datasheet and it confused me.

You are thinking too much, I think. The SparkFun ST datasheet schematic and the one on your circuit schematic are actually showing the same thing. For PNP/NPN transistors (referred to as "bipolar transistors") the arrow symbol indicates the Emitter (mnemonic: think shooting an arrow as emitting), the simple angled line indicates the Collector (a pipe sucking up stuff from the Base), and the Base is obvious, like a table. PNP has the Emitter arrow pointing toward the Base (poke), and NPN has the Emitter arrow pointing away from the base (no poke).
Transistors of the same type/part number can come in different packaging. The packaging we have here is called "TO-92" and with this package, when you are looking at the flat side with numbers on it, leads down, the left-hand lead is always numbered "1", middle "2" and RH lead "3". And for the two transistors you are using, 2n3904 and 2n3906 in TO-92 packages, the leads are 1=E, 2=B, and 3=C left to right as shown on the data sheet.
It makes no difference at all how the schematic
symbol is oriented on the actual schematic, as long as you get the Emitter, Base, and Collector leads wired to the right places in your actual build. For PNP transistors, the Collector is generally connected to the ground or lower voltage part of the circuit, while for NPN transistors it is the Emitter that is grounded or at lower potential than the collector. And simple schematics are generally drawn with the Positive supply rail at the top and the Negative or Ground rail at the bottom. So in this case it was convenient and logical to insert the PNP transistor's symbol "upside down" on the schematic as compared to the SparkFun ST data sheet orientation, since the Emitter of this transistor is connected directly to the +3v supply. (Note that the Emitter of the NPN transistor is connected directly to Ground, and hence logically points down on the schematic.)
