1.) What are the pros/cons of changing my receiving address for every time I receive a bitcoin to my Hierarchical Deterministic wallet?

the best thing you would be doing is avoiding address reuse. and this can protect you against some bugs in some of these HD wallets without you even knowing it. for example the case of blockchain.info reusing k values.
when creating a EC signature you select a random value called k, if you reuse this k your private key can be recovered easily. in this case when you have more than one input in one address and want to spend them you are signing once per input. if your wallet is broken and is giving you the same k, you reveal your private key instantly. but if you have more than one key and only use them once, even if you are reusing the same k it is impossible to recover private key since each key is only used once. https://crypto.stackexchange.com/a/46622/67204
