Hi Josué,

Assuming you are referring to the Human Feb. 2009 assembly (GRCh3/hg19), 
you can find the total size (3,137,161,264) by going to the gateway page 
(http://genome.ucsc.edu/cgi-bin/hgGateway) and clicking the blue 
"sequences" link, which will take you here:
http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg19&chromInfoPage=  (scroll 
down to "Total").

For the number of genes, it really depends on which gene set you want to 
use. For example, the UCSC Genes set contains 27,297 genes. You can 
retrieve this number from the Table Browser: click on 'Table' located in 
the top blue navigation bar. Then set the following:

clade: Mammal
genome: Human
assembly: Feb. 2009 (GRCh37/hg19)
group: Genes and Gene Prediction Tracks
track: UCSC Genes
table: knownCanonical

Then click on 'summary/statistics'. To see the total number of 
transcripts in the UCSC Genes set, change the table to knownGene, and 
click on 'summary/statistics' again.

To obtain the total number of exons, please see this previously answered 
question*:
https://lists.soe.ucsc.edu/pipermail/genome/2007-June/013729.html
*Except set clade: Mammal, genome: Human, assembly: Feb. 2009 
(GRCh37/hg19). Once you have a list, you will need to add the numbers to 
get the total.

I hope this helps. Contact us again at [email protected] if you have 
further questions.
