I'm still a relative newbie, so I'm still learning, but from what I understand, it's safer to go with a slightly stiffer spine than with a weaker spine for the most part. Only thing is, if you go with too stiff of a spine, the arrow won't shoot as well.
Anyway, do a google search for Stu Miller's calculator. I've never tried it myself due to my computer being so old it won't work on it, but I've heard good things about it. It should help you determine the proper spine arrow.
Also, go to Easton's website and look up their arrow selection chart. That should also give you a starting point on what kind of arrow (spine and weight) will work depending on your bow (longbow or recurve), draw weight and length of arrow.
You can also call 3Rivers Archery (one of the sponsors on this site) and ask them for help. They should be able to get you in the right direction depending on the info you give them (type of bow, draw weight, draw length and arrow length). They also sell a test kit of various different spined arrows so you can try and see which ones shoot best.
As for the screw-in inserts, some vendors sell them with the screw-in inserts installed and some don't. If they don't, you can glue them in yourself. I got my 1916 blues online (think it was amazon) cut to length with inserts and field points installed, so that was a plus.
