$3000 was for everything in total im sure you understand.. right now i estimate that im bordering around $2500 - $2600, since the quote i got for the kit iii was about $1900. of course do recommend me other lenses if you know of!
My advise is... stay with your kit lens till you know what you are missing. Everyone here had their own preference for lenses in accordance to their preferred genre and style. So... really no point asking what lens we know of... as a matter of fact, we know of many lenses.
As for what tripod to suggest, well... you can always looked at Sirui and Benro or stay with the tripod that Canon gave you (I highly recommend this option). Both brands offered good quality reasonably priced tripod. Also by knowing your budget is not enough... we do not know what is your intention? What do you prefer.
For example,
1) do you mind the weight of the tripod. If not, get the aluminium alloy ones which is cheaper and still very durable, but they are pretty heavy.
2) Do you want to get the camera as low to the ground as possible, if yes, then you should consider getting one that have a flexible center column, so far I know Manfrotto (only two axis though), Vanguard, Gitzo and Benro offer you this function. Manfrotto and Gitzo might be over your budget though.
3) Do you want your tripod to be packed very small so as to enable easy carrying in your luggage.
4) Are you brand conscious? If not the tripod that came with your camera is actually pretty good, I used my Canon tripod for quite a while and it actually can handle quite a good weigh.
5) what height do you want your camera to be at? Some people are tall, some no so tall, and no one know what height is comfortable for you.
So many questions to ask, I would still recommend that you stay with the free tripod Canon gave you for the time being until you actually know what you want.
