Pasture Improvement

I want to improve my pasture and finding a clear answer on some questions I have is about as simple as pushing a rope.  First, I need to lime my pastures and hay fields.  In the past we have generally waited until fall to do this, but given the weather and timing I have an opportunity to get the lime spread here is June/July, is that a bad idea?  Secondly I need to fertilize my pasture fields, while there seems to be a consensus that too much Nitrogen is a bad thing, the timing seems to have a varying opinion based on the articles I have read.  I have my pastures sectioned off into 8 acres lots, a few lots are poor and not as productive as they should be.  Is there a benefit or negative to fertilizing this fall to perhaps take advantage of a slightly lower fertilizer price?  What about my hay fields?  Or perhaps would I be better suited to split up my fertilizer in the spring instead of fertilizing the hay and pasture fields all at one whack?  Perhaps fertilizing 2 of the pasture fields when I fertilize the hay fields in early April, and the remainder in early May so as to not outpace my forage production with the cattle's ability to keep up pace?  I live in Southern West Virginia if that makes any difference, there is so much data and information that I can't seem to make sense of it to achieve the most bang for my buck!  Thanks guys!
