It seems a bit confused. If I read the intent right, the best way to put the first phrase would be, "As soon as Lisa sees me wearing this expensive designer jumper, she'll think I'm as good as she is." (Lisa sounds like a bit of a snob doesn't she? And hopefully, the person buying that expensive designer jumper realizes that clothes don't make a bit of difference as to what someone is worth - if all they respect is clothes, you don't want them for a friend).) For the second phrase, "Since she received the promotion, she's given me the cold shoulder". (she looks down on me, thinks she's better than me)

1) 'shuffle' refers to movement without much energy, interest, or specific intent or hurry. So one can shuffle down the street (moving without much energy or interest) and shuffling a deck of cards refers to moving them without a specific intent or trying to place them in any order (mixing them). 2) 'Deliberated' refers more to making a decision while taking future consequences of that decision into consideration. Like a court jury will deliberate over the evidence, realizing that what they decide could impact a person's life. Chess players usually take their matches VERY seriously :-) 'Considered' means thought was given to a choice, but not with as much worry or concern for the outcome. For instance, "Next week my parents and I will deliberate about what college I want to go to next year. But for now, I just have to consider what clothes I'm wearing out tonight." 3) 'A curiosity' and 'a rarity' do not mean the same thing, there is a difference. A curiosity could also be called 'an oddity', something noticeable that you may think about for a few moments but not worry about. A rarity is something unusual and uncommon, such as a rare animal. So in the future if many people speak more than one language and it becomes 'commonplace', it is not rare. As a native English speaker, my opinion is you could use either depending on your meaning. 4) It is an incomplete, incorrect phrase or one which has phrasing from a couple of centuries back, which you should not have to learn. It should be written as, 'He has never had to learn good manners' (either his manners are so impeccable that he knows them all, or he is a little monster whose parents/caregivers never taught them). Written as, 'He has never to learn good manners', is phrasing like you'd find in a Jane Austen movie, with the meaning that he doesn't have to learn good manners since he already possesses them in abundance.

Not much, they are both considered 'slang', and refer to someone being a leader or the important head of a group - but usually it is said with humour and not used as a term of respect. Usually people with less status or power than the person being referred to will use such a term, as it is an insincere and slightly derogatory/less respectful term.
