If it takes a bit of retruing after the first 100 miles or so, don't think that your build was less than good. The pros try to avoid that so people aren't bringing their wheels back and complaining. But if it's YOUR wheel, then YOU can retrue it wheneve it needs it. Spokes will seat on the first ride (you may hear some pinging noises) and any small amount of spoke twist will come out. All perfectly normal.
Oil is good, grease is better.
