This bundle comes with a 18-55mm lens, a 55-250mm lens, a telephoto lens (58mm 2x), the super wide angle with macro (adapter), 58mm UV protector filter, auto power slave flash, 8GB & 16GB SDHC cards, tripod & table top tripod, 3-piece filter kit (UV,CPL, FLD), camera case and a backpack, memory card wallet, uSB card reader, and LCD screen protector.
Grand total of $1249. Now, I've never used cameras like these, so is the Canon 70D easy-ish to learn and figure out? Maybe this bundle would be good to get started and comfortable with, and then like you said, expand to more glass for what I'm interested in?
Yeah, I saw some 60mm macros that were a lot less expensive than the 100mm.
Be careful with buying online. A lot of the online photo shops are very shady operations that will try to rip you off in various ways - one of the common ways is by selling you a imported ('grey market') camera, i.e. one intended to be sold in a market other than the US so it won't have a US warranty - then they'll call you up after you order it and offer to sell you their aftermarket warranty service - there are other methods . . . My general rule is that if the price is less than B&H or Adorama, it's probably too good to be true.
Also, regarding super bundles: they usually aren't a great deal because they usually are built around a few good pieces (70d, 18-55 IS and 55-250 are all good quality and good value pieces of kit), but many of the additional pieces are pretty junky quality that you will find you either don't use, or, in the case of the pieces you do use, are of such poor quality that you will want to upgrade soon.
I'd advise you to decide on a body (60d or 70d are both good choices), then decide what lenses you want and see what basic bundles are available with the lens and body you want, and just get the accessories you need to start out (bag, memory card, extra battery) - then start using your equipment and decide what other accessories you want - you probably don't need most of what's in that bundle. I have around $5k worth of gear, but it mostly comes down to body, lenses, tripod, and one filter (B+W CPL)- I don't use adaptor lenses or anything like that.
If you're going Canon (I'm also biased, shooting with an EOS-6D), I'd go with the 60mm EF-S macro for your fish. For other stuff, I had really good results with the Tamron 17-50 f/2.8 (non VC), but the Canon 18-55 IS is pretty good as well (and cheaper); if you want a longer lens, the Canon 55-250 IS and 70-300 IS are both good (the 75-300 is garbage), and the Tamron 70-300 VC is also good. If you want to start getting artistic, the Canon 50 f/1.8 is a great start.

Bump:
If you buy a Canon body and regular Canon lenses, the lenses will work on any camera body you buy going forward. I don't think the L-Series is backward compatible because the new Canon's are much faster than the older ones, but they should be forward compatible.
All EF series lenses (including Ls) are compatible will all EF series bodies, which include every DSLR Canon has ever made. The only incompatibility is with EF-S series lenses, which cannot be used on full frame bodies. I used to have a 20 year old 50mm f/1.8 MK I, it worked great on my (then) brand new EOS-6D - a little slower than newer lenses with USM, but it worked just fine.
