It shouldn’t be necessary to clean much as long as the records are stored in their sleeves, don’t touch the record sides, and so forth.
I wouldn’t say that vinyl is fragile, but it definitely pays to take care of the records.
Tone arm adjustment is possible on a lot of record players and will make a big difference. Different pickups has different requirements for the weight on the needle. On my record player this is adjusted by a counterweight on the tone arm. Is there a local hifi-/record-shop where you can talk to someone about this?
