Car seat confusion

Hiii all

How ru doing? Happy Karthigai deepam...I am in the process of buying baby items, first thing we have to buy is car seat here, whether u have a car or not without car seat they wont allow you to take the kid out of the hospital (!!??), so the thing is we decided to buy the infant rear facing car seat, first we thought of buying convertible car seat, so that we dont have to spend again for car seat after 6 months but the prb with that is u cant carry it around, its heavy and also it has no option to carry around (when I checked it looks like that), so we decided infant car seat, Graco, 8-20 lbs (right?), 5 point harness system...these r the things we have to look right?..so If anyone have good suggestion about it pls do tell me soon. Its tooo late to post it now..coz I want to buy the same in couple of days...just 2 more weeks to my due date...(hee hee)...I checked the craigslist also thinking of buying one from that, convincing price since we have to change it after 6 months I dont want to spend 150-170 dollers on it..(I am planning to buy car seat and stroller together lets see)...

These are the list I made to buy for the baby if there is anything else do tell me....
1. Car seat and stroller
2. Fleece dress, Gloves, cap, shoes (socks i have) - 2 sets min
3. baby bag
4. baby bath items - baby oil, soap, shampoo, lotion, diaper rash cream
5. baby set - cleaning & thermometer
6. Convertible crib - need to check
7. diapers, wipes
8. Infant sling (baby carrier)
9. Head body support stuffs - need to check dont know whether we need this...
10. First aid kit
11. I got the blankets, bathtub and musical bouncer and few (not few more from india) dresses

Is there anything else?

All my well wishers out there pls pray for me to deliver the baby in normal delivery...Baby is little big as per the doctors predictions his head is 10cm, 8 pounds already :-)...so I need your blessings, prayers and wishes..

Thank you in advance :-)
