You should always get to see the dog/s before you make a commitment...the dog you get will be a part of your family for hopefully 12-16+ years, so it is really important to get the right fit. A good breeder will want to meet you and will also want you to meet the pup/s available...will ask you a lot of questions on what you are looking for in a dog...ie just a companion or looking to do agility/flyball or other competitive sports, etc...and will help you chose the pup that he/she feels is the best match for you from a personality type and energy level. Be 100% honest in answering the breeder's questions so that best match is possible. Although Shelties as a breed have certain fairly typical traits, every Sheltie is unique just as every human is unique...hence it is really important to state what characteristics you like and those you hope not to get.
You want to ask what tests (hips, thyroid, eyes, vWD, MDR1. etc.) have been done on the pup's parents and be shown the results. There is never a 100% guarantee that a pup will not have some health issue even if the parents have been tested clear but that chance is much smaller when you know the pup comes from a breeding of two healthy dogs. Very often the breeder will not own both the male and female dog they have bred...but you should get to at least meet the female so you can see her personality.
If you are going the rescue route, ask for as much medical history as might be available on the dog (often there is none)...but as with a puppy it is best, if possible, to meet the dog before you make a decision if this is the right dog for you.
I like both the names you are thinking about...if you google "dog names" there are dozens of sites with literally hundreds of names...it is fun to see all the possibilities.
