"1. Do I enter the date of contribution or the date originally placed in service as the date placed in service." - Date originally placed in service

"2. Do I enter the tax basis going forward (cost less accumulated depreciation) and the remaining useful life or do I enter the total cost, accumulated depreciation and the original method and years of recovery?" Original cost less accumulated depreciation, including any taken on the other return for the 1st part of the year. You then have to force the actual for this year to get the total to come out right. 

If you are doing both return, use the Export Depreciation and Import Depreciation features. You will have to diddle with the current year depreciation to assure no excess.
