We just got back from Eagle River after a year and half. I found this site http://forums.outdoorsdirectory.com/ great for all kinds of fishing/outdoor info.
They are more than willing to help get you pointed in the right direction.
The fish have different run times ie King, silvers, reds, dogs, and pinks. Depending on what you're after, it will dictate where you need to be, when, and what you use.
Ak'ers don't eat dogs or pinks for the most part but are a blast to catch.
Pulling up a 45lb 'but out of Homer, chasing silvers in Seward, and kings and reds on the Kenai make for an unforgettable experience.
My 8y/o son is hooked after pulling out 6-7lb reds out of the Kenai and 20in dollies on Deep Creek on his 8 wt He now says regular fishing is boring. I'm sure he'll hate me later..lol
Other great sites are: http://www.alaskaoutdoorjournal.com/Reports/Fishreport/fishreport.html and http://www.mobilegeographics.com:81/locations/147.html and

Out of Seward for silvers we used Capt Sean from the Fishouse. He's only 20 but had us on silvers all day. When fishing slowed after 15 minutes he'd move us. Great kid!!
Use the forums for other recommendations because there are the bad charters out there if you go that route.
Sorry if the links aren't automatic. I'm still techie slow.
Have Fun!! I'm already planning our next trip.
