Question for 法居士,wojian,dan721

I got a question about to fill out I-485. I am trying to use my friend's house address for mails from BCIS, since I may not live current address too ling. I am not sure how to fill this part shown in I-485 as follow:

-------------------------------------------------------

Address - C/O

-------------------------------------------------------

Street Number |Apt#

-------------------------------------------------------

City

-------------------------------------------------------

State |Zip Code

------------------------------------------------------

I am not sure if both my friend's address and my address need to be filled?

The second question is: for Part 2. Application Type
Do I need to mark h (Other basis of eligibility) and fill out "I-140 pending"?

Thank you so much in advance!
