The TP holder is usually included but not installed since people are particular about where they like their holder. Our TP holder was tossed in the drawer under the dinette seat. Since you say this is a new to me unit, I am thinking you are not the first owner of this unit...the previous owner may never have installed the holder. Just go to Lowe's or Home Depot and pick one out that you like and install it. For the phones, we plug them into any of the outlets using our chargers that we use at home, the AC charger.
Not sure what you mean about the lights.
