Hi antonius,
1. plan your night, figure out what you want to see and what time. try get everything to be as high up (at/near zenith) as possible so you are looking through the least atmosphere. I use Stellarium to assist in this (
http://www.stellarium.org/)
2. plan based on apparent magnitude (lower number = brighter object), start off easy and get dimmer. as time goes by you will be able to see dimmer things with an improvement of technique so also throw a few dimmer objects in as well. If you can't find them review things (compare views now as apposed to six months ago) you have previously seen from your...
3. journal. keep one. place, date, conditions, what you observed, what it looked like, what eyepieces/filters/scope you used, how cross the wife/girlfriend/husband etc was at that time of night, draw a sketch (not of the angry partner, the observed object). So you can review your observations try and improve on them etc.
4. get away from light sources. street lights, large cities, if you smoke understand that lighting a cigarette will blind you, (my girlfriend taking flash photography just as I was getting my night vision), the moon (unless you want to observe it) will "wash out" the fainter objects especially when it is full so try get a night when the moon is out during the day or as close to new moon as possible. (on the left of this page there is a picture of the moon, click it. that will take you to all the info you need in this regard).
5. you mention viewing PANSTARRS, look out for Comet Lemmon too.
6. you mention viewing planets, if your scopes eyepieces accept filters have a go with different color filters, they bring out different details in planets and are between 10 - 20 bucks, which I think make the viewing more of an activity/challenge, but also more rewarding.
7. get a chair/stool so you have a good spot to view from, my back thanks me every weekend.
and just a word on convention; an eyepiece has a focal length in millimeters. the magnification you get is the focal length of the scope devided by the focal length of the eyepiece. So your scope has a 650 mm focal length, your two eyepieces are 25 mm and 10 mm if you got the ones that I think came with your scope, you get 650/25=26x and 650/10=65x. If you wanted ten times magnification you would need a 65mm eyepiece.

Start at low magnitudes, check what time these objects will be at/as close to zenith using Stellarium and go for it.
Finally Welcome to the community, good luck!

very good site for creating a viewing list for the night, lots of options.
