Hay! lucky you RH1 owner!
I daily use my RH910 by recording from my phone / radio either or using good quality 3.5 to 3.5 cable. try getting the shortest 3.5mm cable you can find. i notice the shorter the better sound quality wise.
If your hifi system are posh enough it might even sports a TOSLink Port, then u can use optical cable to record the stuff ( which is awesome in terms of SQ)
I used regular minidisc, and set recording at HiSP it gave me roughly 2 hours. which i rarely use em all. at most 1 hour worth of record.
Dont worry about track splitting, the unit does it for u automatically, and if it doesnt split the songs as u like em, u can always edit them later, directly on your unit with out needing to use a PC.
Later if u find the song u want to keep, just make sure it was split the right way, then delete all the unwanted tracks, after a while u will end up with a disc almost full with your fav tunes, that is when u connect it to the PC, download it to your PC, re arrange them, then burn them back to a disc, label them and put in your shelfs or do what ever you wish with them. then pop a fresh blank to your player, wash, rinse n repeat
