1. If i am taking the jr east pass special, mostly will be 26,27 and 28.But do the japan east pass travels witing tokyo city like ueno, shinjuku, shinagawa all those station
2.Would 7 days pass be more feasible?Looks like my travelling on train is a lot. if i am taking the 7 days pass, i will most likely not take the overnight bus but take the osaka early morning train
Any idea what will be my cheapest mode of travel? thanks a lot

The seven day JR Rail Pass would not pay off, especially as you are taking the night bus to Tokyo.

You don't say what month you are traveling, but the JR East Special Pass would be your best bet for traveling to Echigo-Yuzawa:

The rest of the journeys can be done with single ticketing.

i will go to yamashita and go skiing in kagura resort on the 26th may and back on the 27th may early morning :) Does the east line travel within tokyo? thanks a lot.

Yes, the pass i linked to covers Tokyo.
