Best Thing to do is ........

Save money incase the payment went up for ILR and citizenship

Do training/voluntary work more than 30 hours in a year

Or work to do all those lol coz if working u can save money and do dont need training or voluntary work anymore lol.

And read here about it and always be informed and read the home office websites

And still married to your husband/wife dont forget about that coz thats one of the requirements lol
