Good luck, thats President's weekend, and will be more crowded than normal. There has been a great deal of expansion in the Resort area, so there are a lot of hotels nearby, most with shuttles to the park. If it's within your budget, the Hyatt OC has family Disney suites. Be carefeul about getting too far away from the Resort area, as some of the hotels are less than desirable.
As far as deals on admissions tickets, this time of year is primarily targeted to local residents (which make up 85% of visitorship during the "off" season); that being said, get teh park hopper ticket that matches the number of days you'll be in the area. The tickets are expensive in and of themselves, but the cost is less per day than buying individual tickets.
If you are a CAA/AAA member, they do usually have the best package deals for members.
