Should I reduce store card limits?

Mortgages I believe tend to look at your actual borrowing rather than your limits. If your balances are cleared each month and you have saved 10% of the price of a house, it says something about your approach to money.

Specifically towards a mortgage, it is probably worth culling unused cards and perhaps migrating to more bluechip cards - ie closing the store cards and opening cards with the lowest APRs you can find. Provided you can clear the card each month and that you keep your available credit less than 6 months salary - ideally probably no more than 3 months.
