[CobraGuppy]

Well, the filters are on a 10 gallon that i already have running with mosquito fish (looks like wild guppies)

I will be getting another 10 gallon tank soon though with less scratches so i want to use that tank instead, but, i want to put that tank in the place of the 10 gallon tank i currently have.

Should i just change out my original plan with the mosquito fish keeping the filters cycled instead of the goldfish?

I would do it like this though:
Move the fish to a bin temporarily
move the 10 gallon tank to the floor (or where ever) and then put the filter with the fish in it
Then set up the new tank and all the good stuff (no filter running, maybe air stone to circulate water)
Finally, when i get my shrimp, put the cycled filters on the new tank with the shrimp. The fish i do not have to worry about because i will be giving them to a friend with a pond.

Sound like a good plan?

Oh yeah, and what is your guys' opinion on what filters i should use.

thanks!
