Deductions & credits

@Opus 17 

When you have short term capital gains, you can offset with

1.)Past carryover losses

2.)Investment Interest Expense

 

Question:

1.)Which ones take priority?

2.)If i go with standard deduction every year, can I accumulate the margin-interest(aka investment interest expense), and add it up, until the day I can itemized and offset it in future years?
