Like I said in my other comments, it is what works best for you.
As far as the ledger goes it is very easy to setup, the most important part is writing down your secret passphrase in case you need to recover the wallet. There are a bunch of step by step guides/reviews, some even on Steemit. The wallet software is already loaded on the device you just have to get it setup and download a google chrome app to use it. I believe it comes configured for BTC and ETH. The ledger manager app allows you to add wallets of other currency. I know you are just getting started in crypto, so don't feel like you have to learn everything at once.
To resteem you just hit the arrow looking thing to the left of reply.
