PS1 downloads from PSN

[HOF-city]

These may be stupid questions, but here it goes. I've been playing some PS1 games that i downloaded from the playstation store. I can play them on my PS3 or my PSP. The other day I put in a good amount of time with Wild Arms on my PSP. I felt like playin some more but since I'm home now I'd rather play on my PS3. Is there any way for me to copy the saved game from my pro stick duo to a memory card utility on the PS3, and vice versa when I need to take the game on the road? It would be nice to have my most current saved game on both the PS3 and PSP. The other question. I downloaded Crash Bandicoot and put it on my PSP 1GB memory stick. A couple weeks later I bought a 4 GB memory stick and copied Crash onto that. When I try to play the game it tells me that the game cannot be played using that account. Thanks in advance for any help.
