Seeing as you already have enough UR points for a UA RT ticket at the saver level, I'd concentrate on more UR points and/or United Miles, as particlemn suggested. Although I'd feel a little dirty getting the Chase United at the standard 30k bonus, especially if you're planning on getting into the credit card game for the long haul. I'd wait for the 50/55k bonus offer for that card. Do you have a business or do any online selling, have hobby income, etc? If so, you could get the current offer for the Chase Ink Plus business card for 50k UR points. With the required spend you'd have 55k and if you work the category bonuses right you could easily have over 60k by the time you hit the spend. Even if you're close, looks like you have some United miles already.

More general advice would be to get this all done sooner rather than later. I booked a first class award ticket for my wife and I last August for a flight leaving tomorrow (July 7). I started looking as soon as the schedule was released and by the time I had my ducks in a row, there was one single set of 1st or business award flights available at the saver level on any airline I had enough miles for. And that was with some date and destination flexibility.

On the other hand, economy should be easier to book at the saver level. I booked my trip to Europe last June two months earlier, in April. That was a saver level economy seat, but even then I think I only had 1 or two choices for the date range I was working with.

(I'm also a newbie...always have been and always will be. In case you're interested, you can read about my first award booking here: http://www.valuetactics.com/2015/06/...ts-redemption/ I was in a similar situation to you at the time).
