You can never have too many lumens ...(as long as you can cool it) I currently have about 500 watts of cfls on 4 plants vegging. The red/ blue ratio you have will be fine. The only problem with that 65 watt mogul base cfl is that a lot of the time the separate ballast is going to cost you way more then it would cost to simply purchase a self ballasting cfl of equivalent wattage. I was able to pick up a 55watt 2700k @ wally world for about $10 just to give you an example and home depot carries 42watt 6500k self ballasting lamps for $8 (site to store or delivery only) and since you have 2 plants; 2 of these may work better for your grow. What are the dimensions of you box/ grow area?
