Fred Wilson, Chris Dixon, Brad Feld and others have recently posted about first round funding terms, and helpfully followed with advice and pointers to documents from the law firms Gunderson, Wilson Sonsini and Cooley Godward that will assist entrepreneurs (and VC's) to come to equitable terms.
A site that I have found helpful is Techagreements.com, which hosts a searchable database of a myriad of agreements, by scores of law firms.
In addition, you may want to search Scribd for relevant documents. As an example, here's a search that I conducted on venture financing.
Better transparency in the financing process is good for all.
