Welcome, and excellent vehicle choice. Everyone pretty much already coved engine break in for you. I can't honestly say that I've found any weak points so far with my Si. My advice to you as far as being new to stick is go out and drive your car. There is no other or better way to learn. After a while you will get used to the way your car feels and it will just become second nature to you. Get yourself a full tank of gas and just go cruise around aimlessly so you can get a feel for the transmission. Do some stop and go in an empty parking lot, and try to get a feel for where your clutch engages so your not left rolling backwards and panicking at a stop light on an incline. Also don't rush yourself, be patient, and don't be embarrassed if/when you stall (it happens to everyone eventually). Once you get well suited with the basics there are some more advanced techniques you can look up and practice that can make you more efficient and make your drive just a little more fun.
Things to look up in the future or just for fun:
- rev-matching (great for smooth downshifts and clutch wear)
- heel toe technique
- clutchless shifting (it can be done)
- power shifting (not always great for the clutch)
