Someone answer this IRA/401k quandary for me

I left a job for another in Feb. 2014. Had a 401k from prior job (obviously active into Feb. 2014) that I rolled into a traditional IRA where it now sits. Current job requires one year of employment before qualifying for 401k (Feb. 2015) so I didn't have access to an employer's 401k plan for most of 2014.

At bottom, I have an excess above my emergency fund I need to move somewhere but no idea what is the best vehicle (hookers and blow aside of course).

I haven't maxed a Roth IRA for 2014 yet but plan to. Am I limited to the max Roth IRA contribution at this point? Can I throw a chunk of my savings into my active traditional IRA? Can I max a Roth AND contribute to my active traditional IRA? Trying to figure out what is the best vehicle at this point for tax purposes...
