Hi Frank
Damage looks very superficial to me - I wouldn't be looking to replace any parts. The bend in the reel blade is relatively easily fixed if you are a bit "handy"
You need to secure the blade from moving with a block of wood - placed in & adjacent to one of the blade supports - the with a good sized punch and hammer - bash the blade back into position. I have done this many times and if you are OK with mechanical stuff - easy enough to do with blade still mounted on mower. Once you have the reel blade straight - you should be able to "adjust" the bed knife to make much better mate with the reel and the pair will gradually wear in.
If you aren't comfortable with that path - I guess you will need to take both the reel blade and the entire bed knife assembly (cast backing plate included) to a reel grinding shop to have both reground - should be about $120>$150 but the two blades will come back as good as new.
Removing the two blades is not difficult and I recall there was a short video on how top do it on this site somewhere - maybe someone wiser than me can direct you to it
