I highly recommend VinylStudio as the capture/processing software. It has everything you need from capture, to cleaning, and splitting tracks etc etc. For years I was using iZotope RX for cleanup with Audacity for capture, but VinylStudio does it all.
VinylStudio software makes it easy to transfer your records and tapes to CD and MP3. Runs on both PC and Macintosh Computers and includes a full set of sound cleaning filters.

Then pair it with a high quality ADC, for instance, I'm using:
RME Audio Professional Live, Studio, Recording and Broadcast Solutions. Unrivalled Quality, Performance & Stability MADI Interfaces, Converters & Preamps.

I highly recommend going with the highest sample rate you can when capturing vinyl - I find the higher the sample rate the more transparently "vinyl" it sounds on digital replay, and as a minimum 192/24 (I work with 768/24).
