Eliminating And Replacing Duplicate Records

I am new to sql server and I am having deficulties writing sql script to perform the following:
1) Merging data from two tables A and B
2) Eliminate duplicate present in table B (Conditions to satisfy for dublicate:If similar address is found in both tables AND class type in Table A =1
3) merge data related to dup(eliminated records) to new table.
Not sure if we can eliminate records first before merging two tables. Tables are as follow:

Table A
Fields: ID, NAME, Address, city, zip, Class type
Value:123, John, 123 Main, NY, 71690,1
Value:124, Tom, 100 State, LA, 91070,0


Table B
Field: ID, NAME, Address, city, zip, Class Type
Value:200, Tim, 123 Main, NY, 71690,0 (duplicate; satisfied both conditions and left out in final table)
Value:124, Jack, 100 State, LA, 91070,0 (same condition but second condition is not met)
Value:320,Bob, 344 coast hwy, slc, 807760,0


Final Table:
Field: ID, NAME, Address, city, zip, Class Type
Value:123, John, 123 Main, NY, 71690,1 (should also show t
Value:124, Tom, 100 State, LA, 91070,0
Value:124, Jack, 100 State, LA, 91070,0
Value:320,Bob, 344 coast hwy, slc, 807760,0

Table d:(relate to table A:showing all products that are related to table A)
table_A.ID, Products
123, Paper 1
123, paper 2

Table e:(relate to table B: showing all products that are related to table B)
table_B.ID, Products
200, Paper 3

Final Table:
ID, Product
123, Paper 1
123, Paper 2
123, Paper 3 (changing table b id to table a)

Would appreciate any help writing script to perform such transformation. Thanks
