I read somewhere that you have to open up the account by Dec 31st 2014 if you want to put 2014 money into it. I'm not sure if that's true or not, but if it is, it could be too late for 2014. If you can, I'd do Roth, since your tax rate is going to be low this year, but high in the future, but tIRA is also acceptable.
For 2015, max out your 401k first, then do a tIRA because of the tax break.
For 2016, max out your 401k, then do a backdoor Roth IRA, since that's the only option with your income.
If you have stock options, take advantage of that, if there's an advantage.
When you get more information on your 401k, there could be an option to do a Mega Backdoor Roth:
http://www.madfientist.com/after-tax-contributions/Somewhere around 40% of 401k plans have an after-tax option. I'd do more research on it, some are having issues with it, but maybe by August they will be worked out.
Then the rest in a non-retirement account.
I believe buying a house isn't advisable until later in life, so even though you can afford it, I'd live in a cheap apartment with a roommmate.
If you spend 25k a year on expenses, and make 140k, you'll have ~80% savings rate (because of taxes). 80% means it'll only take 5.5 years to retire:
