As far as waxing goes....You can never over wax! Most new skis are really some what dry and dirty from the factory but just taking them to the local shop for a quick machine wax is just so-so. If you really want to do it right,buy the tools to do it yourself,if you ski alot its well worth it. What i do is this on new skis. First...do a light wipe down of the base with a base cleaner to clean heavy junk from the base,you dont need to soak em down,just damp. Then hot wax and scrape( while still warm ) until the wax comes off clean,about 2-5 times. At this point you can now hotwax for saturation, hotwax , let it dry cool ( a couple hours to overnight ) scrape and repeat as many times as you can, i do this 5-10 times before ever skied. It may seem like alot but really extends the life of the ski and not to mention makes them ski great, if this way is not an option for you,do what you can...any wax is better than no wax, You can then rewax after every couple days of skiing ( depending on conditions ) dirty snow ect: As far as a tune goes,,,,,SKI EM FIRST with the factory tune and see how they ski. Just remember,depending on who makes the ski they will have a factory spec on the base and side angle....1-1 , 1-2 , 1-3 and so on. Most shops set up there equiptment for what ever they decide. Most shops that i know set for a 1-1,,,,so if you like or dislike the factory spec...you have to tell em what you want ( AND HOPE THEY LISTEN ) or do it yourself...its not that hard to do if you have the tools. Check out the many threads around here on this,they are good. Hope this helps.
