Answer 1

You can use
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewStyleGrouped reuseIdentifier:nil] autorelease];
For other labels, you can probably use
[date release]; [tweetLabel release]; [name release]; [myImage release];

Answer 2

You'll have to send a release message to all the objects that you have allocated using init/alloc (name, date, tweetLabel, myImage) as soon as you're finished with them (for example, after addSubview). Note that according to the documentation, the view is retained by the receiver.

Answer 3

try using
NSData *data = [[NSData alloc] initWithContentsOfURL:url];
[myImage setImage: [UIImage imageWithData:data]];
[data release];
data = nil;
In this case, we are manually releasing the memory allocated. I hope, this works
