Don't worry too much about this, you are starting early and asking questions, that's half the battle. It's good to get an early start....heck I have my 2015 US taxes done already.
As Guya says you should probably file separately from your husband if he is not a US citizen to save him (and you) the worry of dealing with his UK assets on US taxes.
You should also file for a filing extension if you have been working in the UK so that you can meet the "bona fide" residence criteria and qualify to use the foreign earned income exclusion FEIE.

You should start by determining your UK tax status.....you could well be a non-domiciled resident and able to use the remittance basis for 6 years free of charge. This means you don't have to pay UK tax on any foreign income that you don't bring into the country, that will be important for your rental income in OH. You will have to pay UK tax on any income and gains you have in the UK, but you will be able to use either the FEIE or FTCs on your US tax return to defray any US tax due.
OH! don't forget OH! I'm sure Ohio will want to tax your OH source rental income.
