Safety Items should be the highest priority. Next on the list are things that if left unrepaired will become a safety issue or drastically increase the cost of the repair. Them would come the items that increase reliability.
- tires (safety)
- alignment (so you don't ruin the new tires)
- parking brake (the odds of a rusty brake line will vary with location) safety
- intake leak (I would first try some inexpensive stop-leak until you can get it fixed)more potential damage if coolant level is low enough to let engine overheat
- strut repair(I would move this above intake leak if the spring is broken) could be a safety item if it is broken or severely worn
- oil change (if the oil level gets low enough it will damage the engine) add oil if needed until it is changed
- fuel filter (reliability) if the filter is plugged you may get stranded but it won't damage anything else
- Any other fluid flushes (reliability) The most important thing do between repairs is to keep the fluid levels up so that more damage doesn't occur. Of course this is subjective since we can't see the car
