This is probably an easy answer, never tried it myself though...
When we switched our isp's, we went from 16 static ip's to what was supposed to be the same however the new isp gave me 3 statics and the rest as a disjointed routed block...the routed block terminates at one of the static ips.....
Is it possible to work this routed block into the same router as the main static ip as a passthrough and then handle them on the back side of the ASA5505 or is this not even possible with the disjointed routed block?

Yes this one is wrong as you said. If the /28 is correct then the subnetmask should be 255.255.255.240 not 255.255.255.248. I'd check with the ISP again.
Having that cleared out. My question to you is what do you want to do with that extra range (xxx.yyy.238.240) ? For example, do you want to assign them to some web servers that you to be accessible from the internet ? If that is what you want to do then YES you can use the static command to map them to your internal server IPs.
Sure, Say you have a web server with inside IP 22.214.171.124 and you want the outside (internet) to be able to browse the web pages on the server. You want the public IP for server to be xxx.yyy.238.241 /28. You use a static command like this
