List dollar amount of small grants on C.V.?
I would say yes. I have done so from when I received my first grant/stipend. I ceased listing once I received a permanent position (or thereabouts) and started getting multiyer grants from national sources. 

As long as you think adding it shows that you are active and competitive (well merited) in terms of receiving the trust to receive money it will be a good thing. You need to constantly evaluate the possible pros and cons of adding informaton to your cv, including funding. I would imagine that being in a soft money situation, listing funding will only be a positive. But, be aware that gaps in your funding stream may become question marks unless they are explicitly explained.
