If you have a fenced in area I highly recommend balls of differnt sizes for kicking and running and chasing and active play with you and dad! You can get a set of 5 sizes of the nice playground balls from Discount School supply online for $13 and I think shipping is another $5..so about $20 for nice quality durable ones. They ship flat so you have to add the air..pumped or compressed would sure be easiest. If you don't have your own compressor, likely someone you know will!
As for a climber..Little Tikes used to make a small cube climber like this..but personally I would not pay what they are asking (I was just looking for the picture for you)..but you should be able to find one around somewhere..or something similar..made for toddlers...

I do home daycare (12 years now) and these are popular..along with swings (but those are not as active!)...but if you have a raised deck you can add a swing real cheap and safe!
Have fun!
