Answer 1

From the official site: http://wiki.nginx.org/HttpRewriteModule#rewrite

difference between break; and last

last - completes processing of rewrite directives, after which searches for corresponding URI and location

break - completes processing of rewrite directives and breakes location lookup cycle by not doing any location lookup and internal jump at all

Answer 2

Module ngx_http_rewrite_module says:

last

stops processing the current set of ngx_http_rewrite_module directives and starts a search for a new location matching the changed URI;

break

stops processing the current set of ngx_http_rewrite_module directives as with the break directive;

last is usual way and used with rewrites way often than break
