Will this transistor/ relay set-up work?

Using Arduino Project Guidance
10

should always have a 125 Ohm resistor?

I could only find a 120 Ohm 1/4 watt resistor. Hopefully it works?

Would this work? http://www.radioshack.com/product/index.jsp?productId=2036270

I also could only find a,
Prv - 400v Max
Vf- 1.2v @ 3A
Industrial Rectifier, will this work?

Thanks so so so much!!
