it will save you some time and aggravation to have them do it. I can't tell you how many times I've struggled to get something to fit.

however now that everything is on and on the way I want them on - I'm maybe happier than if someone else did the work. also there's a good likelihood that you'll want to make some changes.

bottom line - you'll be on the road sooner with less annoyance. this is good because there are lot's of other things to learn and get good at. lots of people get discouraged so the fewer things that stand in your way of your first fun rides, the better.
