This is Kristin...the expert who responded to your question at the beginning. I do think that this is "enough" to believe that she loves you. However, what is more important than what I think, is how it feels to you. If she is doing these things, that is putting love "into action" and it's not just talk. Other things to look for is that she is fairly consistent in her actions and feelings towards you, and that you she seems to enjoy your company, and care about your feelings, etc.
Other than this (combined with the things she is already doing and showing), you don't really need to look for more evidence. Simply believe what is happening in the present time. Otherwise, you risk not being present in the relationship, if you are always wondering and/or questioning her love for you.
Simply accept what she gives to you as it sounds quite good, and trust that it's real. There is no evidence (at all) that would suggest otherwise. Keep that in mind, when you start to have these doubts, that the evidence does indicate that yes, she cares about you and is sincere.
