You should also take off that trim strip and caulk over the screw heads that hold the gutter on. The screw heads are a common point for water intrusion.
Excellent point every external screw is a prime candidate to wick and cause horrendous damage unseen for months or years. I'm a firm believer that caulk of anykind except for the 3M 4000/5000 Marine adhesives/sealants should only be used as a second line of water defense. Exterior lights and their mounting screws and wire penetrations are another great source for water damage. I have developed what I think are fool proof guaranteed methods to take care of these potential issues using a combination of Eternabond double sided and Roof Seal tapes. See the link in my signature for details.

Yes, agree on some form of sealant between siding and metal strip is needed. I'm going to use http://manus.net/products/butyl/64-a-premium/ Found out about this stuff years ago. I was in auto body supply store and a body shop was getting some and told me all the uses they use it for. I picked some up, 50 cent a foot I think. Really great stuff as far as making a superior water tight seal. So much better than the putty tape RV places use. Not so much great stuff if you ever have to remove it. Lots of time to remove as it sticks so good. Put some in my gutter at home as a test maybe 5 yrs ago, still looks new.
Outside of screws, Dicor swabbed on with Que-tip. Wish I had a better way on outside of screws. But haven't found anything (YET) that I can apply and be able to put insert cover back on and when it dry's is still flexible.
