Answer 1

Just move the WHERE condition of the different queries into the defining tuple of the calculated measures:
With Member [Measures].[VenueSalesCost]
as
(
[Chart of accounts].[Main account name].&[Venue Hire Costs],
[Measures].[Amount - Reporting Currency]
)
Member [Measures].[VenueSalesAmount]
as
(
[Chart of accounts].[Main account name].&[Rental of Venue],
[Measures].[Amount - Reporting Currency]
)
Member [Measures].[new Measure]
as
[Measures].[VenueSalesCost] - [Measures].[VenueSalesAmount]
Select {
[Measures].[VenueSalesCost],
[Measures].[VenueSalesAmount],
[Measures].[new Measure]
}
on columns
from [Project accounting cube]
