biro, you are spot on!
YES, Orthodoxy teaches all the same things you mentioned above.
All of Great Lent is spent in contemplative solitude. One does not go to parties, bowling, etc.
Holy Week is especially restricted...by choice and out of respect for the Lord. The fast is the strictest that last week.
Holy Friday is to be very solemn and quiet. Yes, we know the Resurrection is just around the corner....and yet, are we prepared? These are our last days to prepare...so we pray more, read more, etc.
Holy Saturday...Liturgy in the morning...and afterwards, as a female, my day is mostly spent in the kitchen...cooking and baking for the Paschal Feast. However, no TV's are on, no radios, no music, etc. I would even say that the birds are a bit hushed that day. Next year, listen...compare it to the following day - Pascha....when the birds greet the morning in a burst of song...before you've even made it to bed...they are up and joyously singing! That might be my imagination...but, I imagine the same thing year after year! ;-)
Same with Feast days!
Sundays, as well. My mother raised us to do no "work" on Sundays. No laundry. The grass doesn't get cut. No sewing. This can all be accomplished on one of the other 6 days. Sunday is reserved for the Lord's work. After Divine Liturgy, go out and volunteer, visit a nursing home, or stay home and read.
God didn't need to rest on the 7th day, however, He knew that we would.
