Yep just as zip suggested goto the recorded games section and download a few of the Isis recorded games ( there is also a site out there that has a listing of expert recorded game but im not much about posting forum links on other forums )
Now i'm no expert on isis at all, 1680 is about as high as i get and thats probably cause i'm to stubborn to use more hotkeys but you're not as week in classical as you think.
offensivly yes, you are slightly under par compared to the others but if you stay within your base until heroic with towers and mercinaries you're equil to them if not stronger , many times when i first started with Isis i would have a few hopes/hips and invade my base and only having a couple slingers and a spearman or two made i thought i was dead but by not quiting i was able to resist the attack
Although many people have a set god order for Isis , think of the gods as tools and each one will work best for a different job
Example alot of Isis players will go Bast-Nepht for the Eclipse/Ancestors witch is an awesome combo , but against Norse i almost always go Anubus-Hathor or Bast-Hathor for the simple reason mass Petsuchos with a few CA's and axemen mixed in own Norse low pierce armor.
As far as a guide in classical never go all out on counters , what i mean by this is if you're countering Cavelry in classical , hopefully you saw it coming and went Anubus for the spearman upgrade but even if you didnt, just make spearmen w/ priest and slingers. slingers compliment any army as they are good ranged units.
Same thing with countering Infantry ,use axemen w/ priests and slingers.
On a final note learn how to properly use prosperity
always have your 1st mining upgrade and always have a Pharoh empowering a mining camp when you use it . have a atleast 8+ villies on gold , this should give you enough gold to immedietly take 1 TC and be ready to go Heroic when food allows.
Goodluck
