i would also say give your records a damn good clean. it's like getting a bag of new records.
i spent a whole day cleaning a bag of 45 records while i was abroad with some time to kill and i was amazed at the difference. the records sounded so much better, less crackle crisper highs etc.
if you can be bothered i'd seriously recommend it.
i had a go at digitising some vinyl and i found that they just don't have as much punch as the digital tracks and tbh i really couldn't be bothered.
it's far quicker and easier just to buy the tune again in a digital format.
Also even with solid technics there's still going to be a certain amount of looseness in the speed which isn't too much of a problem for myself with Traktor but i reckon with Ableton it could be a bit of a ballache getting it to sync
