You can use confidence instead of lift.

For the second problem, you can (1) set a very small confidence threshold and a very large 
number of rules (e.g. 1000), and then search for the rules you like; (2) construct a data set 
only having income>50k and do the rule mining, where you will have 100% confidence and you can 
use support to rank the rules; (3) balance the data sets, so that both income>50k and 
income<=50 have similar number of instances, and perform the rule mining.

Any of the above three approaches is fine.
