Resampling your audio from 44.1khz to 48khz is a VERY bad idea, as Cross and the sound interface will resample it anyway - you will be resampling it TWICE as I have mentioned - you are not playing it back at the exact same speed, so no, ripping your music at the original rate is the best option.
Another thing which I noticed, when ripping vinyl.. if you DO choose to rip it at a higher sample rate (let's say 96khz) you will not notice a massive difference when playing, but if you are scratching, or decide to move the vinyl really slowly.. you will indeed notice the increased fidelity. It's similar to playing a track at 50% speed - which would normally be half of 44100 which is 22050hz - not very good in comparison. At 96000 half is 48000 so it should still sound as sharp as real vinyl does when played this slowly.
There are problems surrounding this, obviously 96khz files use 2x the processing power - my NEW MacBook Pro 15" cannot handle 96khz AAC files in Cross. However if yours can, or you don't mind the space used by a FLAC (or better, a WAV/AIFF to reduce pressure on the CPU) rip your scratch vinyl at this rate - with a good mixer you should notice the increased fidelity in your headphones, like your original vinyl had.
However I'm going to point this out as unimportant - the quality of sound from general vinyl does not benefit from such fidelity, and is only noticed when you slow it down (as Cross is pumping through twice the samples through it's processes) but it's a gimmick of sound quality - just no-one's gonna notice it
