I am an avid iMac user and have no intention of buying a MacBook/MacBook Air or a trackpad.
I have just installed Lion and have seen Launchpad and Mission Control in my Dock. I could see myself using these lots, but I am concerned that it's not going to be quite as natural as finger-gestures. Will I have to learn keyboard shortcuts or is there something I'm missing?
Will I gain the full Lion experience without a MacBook or a trackpad?

Another way to address your question:
If this is the Mac you're using to make your living, then DEFINITELY run don't walk and get a touch input now. Recommend Magic Trackpad if it's a desktop, but not a strong opinion there.
If you're in college, just in your first job, or in a financial situation where someone bought your Mac for you and the $60-70 for a touch input is pricey - I definitely think you can get by without one without feeling like a 2nd class citizen.
Same answer if you're planning to upgrade soon to another Mac that'll come with one and don't want to pay for one twice.
Otherwise, if you're using this Mac several times (or several hours) a day, I'd say get a touch-based input sooner than later.
If you're only using it occasionally and you're asking because spending another $70 (on a computer you thought important enough to invest $1000+ in, mind you), then I'd wait until you can try it out on someone else's computer.
Finally, if you are considering getting one and $20-30 will make a substantial difference in your decision calculus... keep an eye on discount sites, including Apple clearance online.
Every few months they typically offer discounted refurb devices that are easily as good as buying new.
