first:
you can set the font size in the #+ATTR_LATEX: line with 
#+ATTR_LATEX: :font \scriptsize

second:
If you want to get the numbers rounded, you can either
(a) use babel or
(b) use the spreadsheet capabilities.
In both cases, you'll generate a new table which you want to export

example:

--8<---------------cut here---------------start------------->8---
* orig table                                                       :noexport:
#+name: origtable
|           |     |     <7> |
|      Site | Ind | -log10.pval |
| 123279713 |   1 | 6.006102 |
| 123279713 |   2 | 6.274326 |
| 123279713 |   4 | 6.210920 |
| 123279710 |   4 | 97.163695 |
| 123279710 |   5 | 208.841892 |


* the table formatted with babel
This (untested!) used to work, but due to a bug [fn:1] does not.

#+name: formatorigtable
#+begin_src R :var origtable=origtable :colnames yes
  origtable[,3] <- format(origtable[,3], digits=3)

  origtable
#+end_src

#+ATTR_LATEX: :align p{1cm} p{0.5cm} p{1cm}
#+results: formatorigtable


* the table formatted with calc/orgmode
This is quite complicated but works.

|           |     |     <7> |
|      Site | Ind | -log10.pval |
|-----------+-----+---------|
| 123279713 |   1 |    6.01 |
| 123279713 |   2 |    6.27 |
| 123279713 |   4 |    6.21 |
| 123279710 |   4 |   97.16 |
| 123279710 |   5 |  208.84 |
#+TBLFM: $1=remote(origtable, @@#$1)::$2=remote(origtable,

[fn:1] I am unable to locate the thread about this for some strange reason.
