Also what are some other good EQ practices (like high pass at 20hz-40hz) that are typically standards & what are some good quality SRC software, better than DAW SRC's?
The sample rate convertor will take care of the filtering for you, and the way they implement the filtering is usually a big part as to why many SRCs sound different, so there is no need to eq for this.
I have found that Audiofile Engineerings Sample Manager and Weiss Saracon to be the best options in sample rate conversion. This is just my experience, but I use these these two programs almost daily.
As far as high pass filtering goes, it really depends on the mix. Sometimes high passing at 20hz can free up some headroom in the mix but you really need good monitoring to judge what is best for the mix. So there are no default settings in mastering, you just need to listen to the mix and work out what will give you the best result.
I hope that helps.
