Well, it's good that you're asking, but I'm thinking a starter is optional on this beer. Usually, it's a good idea to make a starter if your yeast is old or if you're making a stronger beer. That Irish Red is 1.044, so you probably have plenty of yeast.
Now if you do want a starter, you usually make a weak wort (like a mini brew session to get a liter or two of unhopped beer), add the yeast to grow more yeast cells (for a day or a week, depending on who you ask), then collect the larger yeast colony for your main beer.
That yeast looks like it has a temp range of 60-72 degrees. If you have a spot in your house that sits somewhere between 60 and 65, that should work out.
