Sounds like you have a nice plan going here.
I would spend more time in the North than South/South West to be fair. Lofoten is just the stone cold nuts. You will be there ahead of the Norwegian/Northern European vacation season, so you might get it a little cheaper than normal, I am not sure.
I can recommend
Reine Rorbuer in Lofoten. If you have a rental you'll blast out there in 90 minutes from Svolvær. Spend a night or two, go on a whale safari. There'll be pretty much 24 hours of daylight in mid June, so prepare for that.
Bergen is a nice place, but not really worth more than one night. Stavanger isn't very interesting other than the surroundings. Oslo is the nut low tbf.
Edit: you can PM me for details, but answering times may vary.
