You could have certain options pre-selected via url parameters - http://mywiki.com/wiki/Special:Block?wpExpiry=indefinite will automatically make the expiry field be indefinite as an example.

If you want a one-click block button from the RC, the best approach would probably be to use JS combined with ajax (That of course requires some programming knowledge though - however its quite likely someone on some wikipedia already came up with such a thing, but i don't know of any off the top of my head).
