Battery Care and Cable for Internet and Keychain :-)

Question

I commend you people for helping out, so thanks!
I have a used sMBP I recently purchased. I noticed that the battery cannot be removed easily like the old MBP I had. Does Apple still recommend letting the battery go all the way down and right before it goes into safe mode, hook it up to power, let it fully charge and try to keep the charge around 60-70% charged? Should I do this "drain and charge to full capacity" once a month? Any reason when I initially hook it up to the white adapter, it does NOT say "charging," but it says" Not Charging." Somebody told me to reset the SMC controller (I think that is the right name) but the person gave me instructions for an older MBP, because what he told me to do did not make any sense
As far as hooking up the MacBook Pro to a wall internet connection should I use this type of ethernet cable or does it not matter? (The ethernet cable that came with the MBP is really loose at the MBP ethernet connection.) "Belkin RJ45 CAT 5e Ethernet Patch Cable (14 Ft.)" If not, any suggestions on the latest recommendation for an ethernet cable? Are there any ethernet internet plugs that take a firewire cable? I know sounds pretty stupid, but I thought I would ask.
Finally, why when I empty the cache n Safari 5.0.4 do some of my usernames and passwords get erased? I thought that would only happen if I "Reset Safari?" If I loose the passwords, are they stored in keychain if I have used them in the past?
thanks

Maybe I'm lucky. But here's my experience.
With the Lumia 800, battery life was poor initially but after a couple of days it impoved, and again too with software updates.
920 now I've had for two weeks and it is the only device I use. Habit I had with all my phones for last couple of years, is to have them charging overnight, with alarms set and in main profile for calls (text on silent). Same still with 800 and 920. Though both happily went through the night if I didn't plug them in.
920 originally battery wasn't great, but improved daily after about 3-4 days. This morning I took it off charge at 07:00, and it's still going strong at 21:30. Been on wi-fi, 3g, phone calls & texts in/out, podcast update check download and playing, email and calendars syncing. A fair amount of speech to text for calling and sms. Whatsapp, NFC and Bluetooth on all day. Screen brightness on 'high', Timeout at 3 mins. Much use of Facebook. Twitter, internet browsing, email, Bluetooth transfer, NFC writing and reading. Taken a couple of photo's and videoes, some Youtube viewing, and about half hour of games. Cloud Backup for text messages 'On', transferred photo's to skydrive and downloaded OneNote while away from wifi. Used several apps a few times throughout the day on wifi and/or 3g. Been on the Store.
Battery says 18% and 12 hours remaining. I think time remaining is somewhat misleading (as it's based on recent usage I suspect), but the percentage seems reasonably accurate, having checked it throughout the day.  I plan to keep using it tonight for setting up more items on Nokia Reading, listening to music, some sms stuff, along with Facebook and Twitter mainly and will see when it dies.
