To be honest, I'd pass on that kit. that listing is padded like crazy to make it seem like there is more there than there actually is, and what is there is not good quality.
The third and fourth lenses in that kit aren't actually lenses, they are screw-on wide-angle and telephoto converters. Which isn't necessarily bad, but if you are going to use converters of that sort, you should always stick with the camera manufacturers brand, so in this case Canon. Focus is always dubious at best when using third-party converters.
The tripods included there will both be worthless. The last 7 items shown are part of the standard camera package, and are included even if you only buy the body. The hardshell case might be good, though its hard to say without them even mentioning a brand. The soft case looks alright.
The two Tamron lenses should be fine, though 28mm is the widest they go (without the wide angle converter), and that isn't wide angle at all on the crop sensor in the T2i.
I would probably opt for something more like This kit from B&H
. The lenses aren't quite as long, but you do get optical stabilization, which is a big improvement over the Tamrons in the other kit. And they get you down to 18mm on the wide angle end. There aren't as many bells and whistles included, but its also cheaper, so you can select a couple of additional accessories and buy good ones to start with, then add onto your kit as you go. I'd recommend a couple decent size memory cards, (you don't necessarily need the super-fast expensive ones if you aren't doing video work) an extra battery, a case of some sort, and a set of filters to start with (UV and polarizer). You'll probably find a smaller soft case more convenient than that big hardshell, unless you are carrying lots of gear on photo expeditions.
