It's normally recommended that young bunniesaround eight months old start slowly switching to a limitedpelletand veggie diet, soa year-old rabbit is wellwithin the range, and your bunny looks very healthy and VERY cute!
The alfalfa concerns areweight but also high calcium andprotein levels, soyou may want tomix some Timothypellets in with the alfalfa and see how that goes. You'llfind that many people feed their rabbits alfalfa pellets, and they havefor years with no dire consequences. But it always depends onthe bunny. Veggies also contain calcium, so that's anotherreason to think that the levels in the alfalfa pellets may be tolerable(although veggies contain water which helps wash out thecalcium).
The rule of thumb is an eighth to a quarter cup of pellets twice a dayfor each five pounds of body weight, but if she doesn'teatveggies,I'd think more pellets are necessary, and if Nickysaysa cup is fine, I believeher.
You'll find endless debates about pellet diets vs. vegetable diets,alfalfa vs. timothy pellets, etc, even among vets. so there reallyareno cut and dried rules. Again, it depends on thebunny. Watch for urinary problems likeslugeandkidney stones,and make sure she drinks.
I also agree with Nicky thatyou shouldn't limit the timothyhay, though. It'sa better source of fiber than thepumpkin and oats, which can add also calories (which may or may not bean issue), so if she likes her hay, you shouldn't have aproblem.
It sounds like you've doing fine, so far, so good! Keep us posted on how she's doing!
