AFAIR the official way to suppress unwanted messages is warn.conflicts=FALSE so the user probably wants to issue library(Hmisc, warn.conflicts=FALSE).
As of 'verbose' - it is not by default TRUE - it's actually determined by the current "verbose" option, so users can actually change the default as desired.
On the other hand .First.lib takes only two, fixed arguments, so AFAIK you cannot pass any additional arguments from outside (I believe this applies to .onLoad and friends, too).
In fact I'm not quite sure what you want to "fix" here .. is it the wish in general to be able to pass arguments to packages while being loaded? In your specific case I'd say you don't need that since you have always access to the 'verbose' option ...
