I highly recommend basic maintenance and going over things like the EGR passages, making sure your heat blows hot (no plugged heater core), making sure the lines to your throttle body aren't plugged up, cleaning out and/or replacing the PCV valve, shifter linkage bushings, and the obvious wear items like plugs, distributor cap, etc.
I'd also highly recommend a compression test. These cars tend to be neglected by their thrifty owners and it isn't super uncommon for the engine to be rebuilt by the mileage you have already. My engine is a hair under 130k miles and it is down to 130 psi per cylinder (195 is the spec I believe). I'm really curious how much efficiency I'm loosing due to that.

Thanks for the advice!
I picked up a bunch of stuff at O'reilly's today. Some maintenance, some ecomodding.
1) New spark plugs
2) New air filter
3) a bunch of new light bulbs
4) 5w-30 castrol synthetic
5) seafoam
6) new wipers
7) rust remover (small patches here and there, I want to stop them from spreading)
8) Carb cleaner for EGR and PCV Valves. (Check engine light came on last night for EGR)
9) Headliner adhesive spray
10) Compression tester so I'll find out what kind of shape it's in. If the compression is really low, what do you think should my next steps be? Other Geo Metro forums suggest rebuilding the head. There is a member/mechanic that specializes in Geo's and offer's "head rebuilding" for $250. Not a bad deal.
Ecomods:
1) Deep Cycle battery
**Updates: I did a short fillup to get my SGII calibrated (I know i should've waited for a full tank but I was too excited to see preliminary results), and I got
58 MPG! I wasn't even hypermiling that hard, just basic P+G and DFCO. Also impressive because I was stuck in Los Angeles Traffic for half of the time with stop and go driving.
