I'm as new as it gets when it comes to photography. I just remember I took two years of photography back in high school and I thoroughly enjoyed it. Now that I'm making some money, I want to invest in this hobby again! Trust me, it's been ~ 7years since I took those classes, so assume I know nothing, because I really don't! I understand the concept behind aperture and shutter speeds, but no way am I able to adjust them on the fly (yet hopefully!).
I'm looking to get a refurbished Canon T2i along with the 18-55mm kit lens. I am also looking to get the "Nifty Fifty" 50mm 1.8II lens as recommended by people on my car forum, and my labmate, who is a photographer and knees deep in investment, so I figured he must make some sense.
My primary focus will nature shots, twilight hours shots, night shots, foul weather shots, and macro shots. Do you think the T2i will be sufficient? I'd like to keep it for at least 6months-1year as I learn with it. Having said that, do you think i'll outgrow it quickly? If you know of other camera without going over $800, please suggest away!
What macro lens would you recommend "just to get started"?
Also, what about tripods? Common sense tell me I want something that's light enough to be portable, but sturdy enough to withstand some wind and the overall weight of a dSLR w/lens. Flexibility is high on my list, I'd like the ability to shoot close to the ground. I understand I'm asking a lot from the tripod, but if there is one in the range of $100-150, that'll be great! 
Please, humble me with your knowledge and experience, and I am definitely open to constructive criticism! Thank you much.
