Intro, context and recommendations

Hello,
I am 27 and up until a few weeks ago I wasn't really interested in fragances, but I am coming around and wanting to learn more about them and whatnot. I seek some recommendations as to what would suit my needs and also a couple of questions in general.

Before two weeks ago I pretty much went with what I was given as Christmas every year, which meant that while growing up all I used was this one thing called Junior by Lacoste and then Hugo by Hugo Boss from my late teens to a couple of years after college. Recently I was given a bottle of Boss Selections by Hugo Boss which I like more than Hugo. I am looking for fragances to use in an office environment (I currently use the Boss Selections for that) and casual outtings (I recently bought DKNY Be Delicious and I am using it for that). I live in Toronto, so I guess I need to look up fragances for all the seasons, since I want to built a proper wardrobe, but I want to start with things I could use for this summer and built up from there, so I was hoping for some recommendations.

I was currently looking into buying several decants to test out, and what I had in mind was this:

Terre d'Hermes - think I would use this one going out during th day and whatnot
Aqua by Bulgari - same as above
Caron Le 3me Homme - offce, maybe?
Vetiver by Guerlain - more casualness
Creed Himalaya - winter/formals
Rochas Man - going out at night

Do these sound like solid choices to try on?

Sorry if the post is all over the place by the way. I hope I am posting it in the right place... any advice will be greatly appreciated.

So, I think the images I had originally posted stopped working, so I edited them out and now putting them back in:

Tried this and really liked it


I saw it yesterday at a Marshall's-like store in Canada and bought it:


These two smell quite different. I was wondering if they are supposed to be the same, since they share name. Or can perfume "go bad" or something along those lines? Or are these two supposed to be different fragrances?

And about the first post, any help that anyone could provide to this newbie as to where to start would be appreciated.

Thanks for the suggestions everyone. I will look into them.

Also, I learned that the version of BL I bought is now being sold as just Burberry for men. This happened in 2006 when the current BL was launched or something along those lines. There was nothing wrong with this fragrance but I found myself not liking it as much as the BL so I ended up returning it with no issues.
